Answer:
Here you go
Step-by-step explanation:
Answer:
a. 0.17
b. 0.95
Step-by-step explanation:
The key to answering both questions is that we should understand that the probability of an event happening = 1 - the probability of the event not happening
Firstly, we want to calculate the probability of less than four
Probability of less than four = 1 - probability of four or more heads
that is 1 - 0.83 = 0.17
Probability of less than 8 = 1 - probability of 8 or more = 1-0.05 = 0.95
(X+5)(x-7)
Perform FOIL
x^2-7x+5x-35
Add 5x to -7x
<span>Final Answer: x^2-2x-35</span>
They are 64, 128, and 256 i do believe
