Question

1. If three coins are tossed,which is NOT a possible value of the random variable for the number of tails?

Answer 1

If three coins are tossed then sample space-

sample space- { HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

Then Random variable X can have the value $0,1,2,3.$

The Random cannot have the value N-{0,1,2,3}
