We will use the Binomial probability formula to find the answer
The formula is given by ⁿCₓ (p)ˣ (1-p)ⁿ-ˣ
We have
n, the number of trial = 16
x, the sample we aim to try = 7
p, the probability of success = 0.5
Substitute these values into the formula
P(7) = ¹⁶C₇ (0.5)⁷ (1-0.5)¹⁶⁻⁷
P(7) = 0.1746 (rounded to four decimal places)
The cost would be $4.74. 3.95 times 0.2 is 0.79. Add that to 3.95 and get 4.47
Answer:
exact form: -17/8
decimal form: -2.125
mixed number form: -2 1/8
Step-by-step explanation:
cmon this is freaking addition
The answer is going to be 1 and -4 as the 2s cross divide out
