I'm assuming you're subtracting. It would be 3.9. The second one would be 0.65.
Answer:
6.9, and it is greater by 0.195
Step-by-step explanation:
Answer:
1/6 pan of brownies
Step-by-step explanation:
It is given that probability of a student being on the debate team is 0.42
So, P(D) = 0.42
It is given that probability of a student being on the math team is 0.26
So, P(M)= 0.26
The probability that he is on both teams is .20
So,
We have to determine the probability his is on the math team if we know he is on the debate team. This is the case of conditional probability.
So,
= 0.476
= 0.48
Therefore, the probability that he is on the math team if we know he is on the debate team is 0.48.
Option 1 is the correct answer.
