Answer:
0.68
Step-by-step explanation:
Given that :
P(trombone | snow) = 0.8 ;
P(trombone | no snow) = 0.5
P(snow) = 0.6
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(no snow) = 1 - 0.6 = 0.4
Hence,
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(trombone) = (0.8 * 0.6) + (0.5 * 0.4)
P(trombone) = 0.48 + 0.20
P(trombone) = 0.68
Since this is out of 4, you can think of 4 as being 1. Now each part of 4 needs to have an equal value so you need to split 1 into 4 equal values. So half of 1 is 0.5 and half of 0.5 is 0.25. So, each part of 4 has a value of 0.25.
1/4 = 0.25
2/4 = 0.50
3/4 = 0.75
