Ultrasound is a widely used technique to predict the sex of an infant before birth, however, sometimes the prediction is incorrect. Information is available on 1000 births, of which 480 were female and 520 were male. Of the 480 female births, 48 of them were predicted to be male by ultrasound, while of the 520 male births, 75% of them were correctly predicted by ultrasound. If a newborn is chosen at random from this population: (a) What is the probability that the ultrasound predicted that the infant would be female? (b) What is the probability of the ultrasound test being correct when it predicts that the unborn infant will be female? (c) What is the probability of the ultrasound test being correct when it predicts that the unborn infant will be male? Plzz solved all question then i will rate you

A group of people were asked if they had run a red light in the last year. 478 responded "yes", and 254 responded "no".Find the probability that if a person is chosen at random, they have run a red light in the last year.
In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 211answered "none,"289 said "one," 373 said "two," 143 said "three," and 138 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05.
Suppose a math class contains 37 students. There are 19 females (six of whom speak Spanish) and 18 males (five of whom speak Spanish). Give all answers as decimals to at least two decimal places.1. What is the probability that a randomly selected student speaks Spanish, given that the student is female? 2. What is the probability that a randomly selected student does not speak Spanish, given that the student is male? 3. What percent of Spanish speaking students are male? 4.

This problem involves empirical probability. The table shows the breakdown of 86 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the Army.

According to recent passport data, the percentage of people in a particular country who have a passport has risen dramatically. In 2007, only 30% of the country's citizens had a passport; in 2017 that percentage had risen to 45%. Assume that currently 45% of the citizens have a passport. Suppose 45 citizens of the country are selected at random. ... a. Find the probability that fewer than 18 have a passport. The probability that fewer than 18 have a passport is (Type an integer or decimal. Round to three decimal places as needed.)
According to a recent study, 3 in every 8 women has been a victim of domestic abuse. This probability was obtained from a survey of 1,000 adult women. Suppose we randomly sample 25 women and find that 7 have been abused. Complete parts a through c below. G a. What is the probability of observing 7 or more abused women in a sample of 25 if the proportion p of women who are victims of domestic abuse is really p= ㅎ? The probability of observing 7 or more abused women in a sample of 25 is (Round to four decimal places as needed.)
