Two candidates, Dan and Donald, run for class president. Two other candidates, Freddie and Bernie, run for vice president. Each candidate has a 50$\%$ chance of winning. What is the probability that both Dan and Freddie win

0.25

Step-by-step explanation:

Event of winning Dan or Freddie are both independent.

For independent events A and B , P(A and B)= P(A). P(B)

Since, P(Dan win)= 0.50 and P(Freddie win)= 0.50

So, P(both Dan and Freddie win) = P(Dan win) . P(Freddie win)

= (0.50)(0.50) =0.25

Hence, the required probability = 0.25
