Answer:
0.84 is the required probability.
Step-by-step explanation:
We are given the following in the question:
Probability that a child eats popcorn and cotton candy = 0.58
[tex]P(p\cap c) = 0.58[/tex]
Probability that a child eats popcorn = 0.69
[tex]P(p) = 0.69[/tex]
Probability that a child eats cotton candy = 0.87
[tex]P(c) = 0.87[/tex]
We have to evaluate the conditional probability that a child eats cotton candy given that the child has already eaten popcorn.
[tex]P(c|p)\\\\=\dfrac{P(c\cap p)}{P(p)}\\\\=\dfrac{0.58}{0.69}\\\\=0.84[/tex]
0.84 is the probability that a child eats cotton candy given that the child has already eaten popcorn.
