If we choose four numbers from 1 - 20, what is the probability that 6 or 10 will be among them?

Correct answer:

p =  0.3368

Step-by-step explanation:

C3(18)=(318)=3!(183)!18!=321181716=816 C1(2)=(12)=1!(21)!2!=12=2  C4(20)=(420)=4!(204)!20!=432120191817=4845  p=(420)(12) (3202)=48452 (3202)=9532=0.3368
