Arlecino [84]

Answer:

P(B)= 0.305

Step-by-step explanation:

Hello!

This exercise is an application of conditional probabilities.

You know that the definition of a conditional probability is:

P(A/B) = \frac{P(AnB)}{P(B)}

And

The probability of A occuring, given that B has already ocurred is P(A/B)= 0.61

The probability of A and B ocurring at the same time is P(A∩B)= 0.5

You can clear the probability of B from the equation:

P(B)= P(A/B)*P(A∩B)= 0.61*0.5= 0.305

I hope you have a SUPER day!
