Each friend gets 1/18
Because 1/6 divided by 3 is 1/18
<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
Solution
A=4πr2=4·π·82≈804.24772
Approximately = 804.25
The answer should be -14/16
