Answer:

P(A\textrm{ and }B)=\frac{3}{14}

Step-by-step explanation:

Given:

P(A)=\frac{4}{7}

P(B|A)=\frac{3}{8}

We know that, conditional probability of B given that A has occurred is given as:

P(B|A)=\frac{P(A\cap B}{P(A)}. Expressing this in terms of P(A\cap B), we get

P(A\cap B)=P(B|A)\times P(A)

Plug in the known values and solve for P(A\cap B). This gives,

P(A\cap B)=P(B|A)\times P(A)\\P(A\cap B)=\frac{3}{8}\times \frac{4}{7}\\P(A\cap B)=\frac{12}{56}=\frac{3}{14}

Therefore, the probability of events A and B occurring is \frac{3}{14}.

Chad and Victoria are playing a game with a quarter and a spinner divided into sixths numbered one through six each player spins
rodikova [14]
The simple way to do this is to multiply the number of outcomes of one object times the number of outcomes in the other object. In this case a quarter has 2 sides, heads and tails. Since the spinner has 6 sections, there are 6 outcomes.


With this we can do, 2x6=12.

Therefore there are 12 outcomes
