Question

A no. Is choosen at random -3,-2,-1,0,1,2,3 find the probability which is less than 0 ir equal to zero

Answer 1

Total no. of events= n(S)

no. of favourable events = n(E)

Probability of a favourable event to happen = P(E)

n(S)=7

n(E)=4( you want 4 numbers to be chosen (-1,-2,-3,0))

P(E)= n(E)/n(S)

=>4/7.
