At an amusement park, the probability that a child eats popcorn and cotton candy is 0.58. the probability that a child eats popcorn is 0.69 and the probability that a child eats cotton candy is 0.87. what is the probability (rounded to the nearest hundredth) that a child eats popcorn given that the child has already eaten cotton candy?

hint:
p(a|b)=p(a∩b) / p(b)

0.84

0.67

0.79

0.40

The correct answer option is 0.67.

Step-by-step explanation:

We are given that the probability that a child eats popcorn and cotton candy is 0.58, probability that a child eats popcorn is 0.69 and the probability that a child eats cotton candy is 0.87.

We are to find the probability that a child eats popcorn given that the child has already eaten cotton candy.

P (eats popcorn and has already eaten cotton candy) = = 0.67

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

answer: -1
