If three prime numbers are randomly selected from the prime numbers less than 30 and no prime number can be chosen more than onc
Dmitry [639]

Answer:

C)30%

Step-by-step explanation:

Prime numbers less than 30 are given below

2,3,5,7,11,13,17,19,23,29

We have to find the probability that sum of three prime numbers selected will be even.

We know that

Sum of any three prime number except 2 will be odd.

Total prime numbers except 2=9

Total prime numbers=10

Probability:P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Probability of getting sum of three prime numbers selected will be odd=\frac{9C_3}{10C_3}

nC_r=\frac{n!}{r!(n-r)!}

By using formula

Probability of getting sum of three prime numbers selected will be odd=P(E)=\frac{\frac{9!}{3!6!}}{\frac{10!}{3!7!}}=\frac{9!}{3!6!}\times \frac{3!\times 7\times 6!}{10\times 9!}

Probability of getting sum of three prime numbers selected will be odd=P(E)=0.7

Probability of getting sum of three prime numbers selected will be even=P(E')=1-0.7=0.3=0.3\times 100=30%

By using formula P(E')=1-P(E)
