Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 ×
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 ×
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 ×
+ 15C5 × 
P =
( 15C8 + 15C5 )
P =
( (
) + (
) )
P =
( 6435 + 3003 )
P =
( 9438)
P =
( 4719)
P = 
P = 0.29
