Answer:
35/128 ≈ 0.2374
Step-by-step explanation:
The number of combinations of 7 things taken 3 at a time is ...
7·6·5/(3·2·1) = 7·5 = 35
The number of sequences in which the coins can land is 2^7 = 128.
Of those 128 sequences, 35 will have exactly 3 heads.
The probability is 35/128.

Answer:
A = $13,660.81
Step-by-step explanation:
P (principal) = $4,800.00
I (interest) = $8,860.81
First, convert R as a percent to r as a decimal
r = R/100
r = 6.2/100
r = 0.062 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,800.00(1 + 0.062/4)(4)(17)
A = 4,800.00(1 + 0.0155)(68)
A = $13,660.81
