If you a flip a coin 6 times, what is the probability that you will get exactly 4 times?

1 answer:

7 0

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.

Answer:

y = $-\frac{5}{2}$ x - 1

Step-by-step explanation:

5x + 2y = 12

2y = -5x + 12

y = $-\frac{5}{2}$ x + 6

y = mx + b

4 = $-\frac{5}{2}$ ( -2 ) + b

4 = 5 + b

b = -1

y = $-\frac{5}{2}$ x - 1
