Consider the events "it is night" and "it rains" are mutually exclusive events. Find the probability that it rains and it is night if P(it rains)=0.1 and P(it is night)=0.5.
Read Solution (Total 7)
-
- let a=it is night
b=it rains
a and b are mutually exclusive event so p(ab)=0
hence probability of it rains and it is night =0 - 9 years agoHelpfull: Yes(12) No(4)
- ans-0.05
as both are mutually exclusive events,the resultant probability is product of their probabilities
P((it rains) and (it is night))=0.1 *0.5=0.05. - 9 years agoHelpfull: Yes(6) No(6)
- P(AUB)=P(A)+P(B)=0.6

- given the both events are mutually exclusive evensts. the we should multiply both th events .
p(A)*p(B)= 0.05 - 8 years agoHelpfull: Yes(2) No(2)
- Two events are mutually exclusive if they cannot occur at the same time.
So the required probability =0 - 8 years agoHelpfull: Yes(2) No(1)
- P(AUB) = P(A)+P(B) = 0.1+0.5 =0.6

- given mutually exclusive ...hence p(ab)=0 and also p(aub)=p(a)+p(b)-p(ab)=0.6
- 8 years agoHelpfull: Yes(0) No(1)
