Question

based on for 43% of adults believe in reincarnation assume that 6 adults are randomly selected find the P at least 3 of 6 believed in reincarnation

Answer 1

P = 43% = 43/100 = 0.43%

Q= 100 -43 = 57%=57/100= 0.57

n= 6

r=3

The probability that at least 3 of 6 believed in reincarnation is

`n^{}_(c_r)* P^r* Q^(n-r)`
`\begin{gathered} =6_(c_3)*0.43^3*0.57^(6-3) \\ =20\text{ }*\text{ 0.079507}*0.57^3 \\ =0.2945 \end{gathered}`
