The first one would be 190 and the second one would be 107
Answer: x/y that is distance/ speed which is the formula for time
Step-by-step explanation:
Answer:
14) b) P(B/A) = 0.50
15) P(A or B) = 0.7
Step-by-step explanation:
14)
Given P(A) = 0.4 and P(B) = 0.5 and P(A and B) = 0.2
Conditional probability of B given that A

15)
By using Addition theorem on probability
P( A ∪ B) = P(A) + P(B) - P(A∩B)
= 0.4 +0.5 - 0.2
P( A ∪ B) =0.7
19/21 would be your answer
