Aron flips a penny 9 times. which expression represents the probability of getting exactly 3 heads?

Step-by-step explanation:

We know that Aron flips a penny 9 times and gets exactly 3 heads .

Probability of getting a head or a tail is .

Here, we need to find the probability of getting exactly 3 heads:

So the expression representing this situation will be:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

there are infinitely many solutions.
