Probability that you will get exactly 4 tails, if you flip a fair coin 7 times is: 
Step-by-step explanation:
We need to find the probability that you will get exactly 4 tails, if you flip a fair coin 7 times.
This is the combination question.
The total combinations will be: 2^7=128
Now, finding number of ways we can get exactly 4 tiles:
We will use the formula:
in our given question, n= 7, k= 4
Putting values:
So, Probability that you will get exactly 4 tails, if you flip a fair coin 7 times is:

7,393,420,225 is the answer tk the problem without using calculator.
Responda:
6 meses
10 meses
Explicação passo a passo:
Dado que:
Principal = 4000
Juros = 586
Taxa (r) = 29,3% ao ano = 0,293
Juros simples = principal * taxa * tempo
586 = 4000 * 0,293 * t
586 = 1172t
t = 586/1172
t = 0,5 anos
Tempo = (0,5 * 12) = 6 meses
B.)
principal = $ 90909,09
Montante final = 100.000
Taxa (r) = 12% = 0,12
Usando a fórmula:
Quantidade final = p (1 + rt)
Taxa = r; t = tempo
100000 = 90909,09 (1 + 0,12t)
100000 = 90909,09 + 10909,0908t
100000 - 90909,09 = 10909,0908t
9090,91 = 10909,0908t
t = 9090,91 / 10909,0908
t = 0,8333334
Número de meses:
0,8333334 * 12
= 10 meses
