Answer:
0.66
Step-by-step explanation:
Given:
Let P(Throwing strike) = 0.35
So,
P(S') = 1 - 0.35 = 0.65
P(A / B) = P(A and B) / P(B)
P(Throwing fastball and thrown strike) = P(F / S) = 40% = 0.4
P(Throwing fastball not thrown strike) = P(F / S') = 80%
P(Throwing fastball not thrown strike) =0.8
So,
P(F and S) = 0.8 x 0.65
P(F and S) = 0.52
P(F) = [P(F / S) x P(S)] + [P(F / S') x P(S')]
= (0.4 x 0.35) + (0.8 x 0.65)
= 0.14 + 0.52
= 0.66

Step-by-step explanation:
Answer:
The speed at which Anna travel with her bike is 3 miles per hour .
Step-by-step explanation:
Given as :
The distance cover by Anna = 6 miles
The time taken by the Anna to cover the distance = 2 hours
Let The speed in miles per hour = s miles per hour
<u>Now, As we know </u>
Speed = 
So, s = 
or, s = 3 miles per hours
So, Speed = 3 mph
Hence The speed at which Anna travel with her bike is 3 miles per hour . Answer
