Find the probability that the student will guess correctly on at least 1 question.A student takes a multiple choice test that has 10 questions. Each question has five choices. The student guesses randomly at each answer. Find the probability that more than four of them fail the test.
- Toss a balanced coin independently 10 times. Assume that the number of Head and the number of Tails follows Multinomial Distribution. Find the probability to obtain 3 Heads and 7 Tails. Calculate MEAN and VARIANCE.Activity 1- Data Collection The concept of chance can be demonstrated by tossing coins. It is usually impossible to control whether the coin will land heads up or tails up. That is said to occur by chance. Since there are two possible outcomes, each with a ½ probability, it is expected that when a coin is tossed many times approximately half the tosses will land heads up, and half will land tails up. Toss a single coin 50 times and record the results in Table 1.1. Calculate the expected number of heads and tails to determine the deviation (0-E). Indicate whether each deviation is a positive number or a negative number. If the deviations are small, you can attribute them to chance. If they are large, then you must attribute them to some reason other than chance.
