Transcribed Image Text:Suppose that the genders of the three children of a certain family are soon to be revealed. Outcomes are thus triples of "girls" (g) and "boys" (b), which we
write gbg, bbb, etc. For each outcome, let R be the random variable counting the number of girls in each outcome. For example, if the outcome is bgg, then
R(bgg)
= 2. Suppose that the random variable X is defined in terms of R as follows: X= R“ – 2R-3. The values of X are given in the table below.

Transcribed Image Text:A binomial experiment with probability of success p = 0.75 and n=7 trials is conducted. What is the probability that the experiment results in exactly 3
successes?
Do not round your intermediate computations, and round your answer to three decimal places. (If necessary, consult a list of formulas.)
