Discuss the effect of CO_2 concentration on opening and closing of stomata.

For three events A ,B and C ,P (Exactly one of A or B occurs) =P (Exactly one of B or C occurs) =P (Exactly one of C or A occurs) =1/4 and P (All the three events occur simultaneously) =1/6dot Then the probability that at least one of the events occurs, is : 7/(64) (2) 3/(16) (3) 7/(32) (4) 7/(16)
