There are n socks, 3 of which are red, in a drawer. what is the value of if, when 2 of the socks are chosen randomly, the probability that they are both r e d i s 12 ?

Respuesta :

n=4  is the value of if, when 2 of the socks are chosen randomly, the probability that they are both r e d i s 12.

What is the probability in simple terms?

  • Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
  • Statistics is the study of events that follow a probability distribution.

Number of socks = n .

Number of red socks = 3 .

Given

       3C2nC2=12

     ⇒nC2=3×2=6

    ⇒n=4
