(a) less than 4 (b) odd (c) less than 4 and odd (a) find the probability that the number selected is less than 4. pr(less than 4)equals one third (type an integer or a simplified fraction.) (b) find the probability that the number selected is odd. pr(odd)equals five ninths (type an integer or a simplified fraction.) (c) find the probability that the number selected is less than 4 and odd. pr(less than 4 and odd)equals nothing (type an integer or a simplified fraction.)
