Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
With the help of theorems involving circles, assuming that arc ABC is a central angle (meaning both legs of the angle start from the centerpoint), the measure of the inscribed angle is twice that of the central angle. Thus, arc AC is equal to 2*40°= 80°.

Answer:
17 wins
Step-by-step explanation:
Given
P(winning) = 1/5
Number of games = 85
The number of winnings could simply be calculated as the product of the probability and number of games played.
Expected number of winning : P(winning) * number of games
Expected number of winning = 1/5 * 85 = 17 wins
