2/0 = 2
Answer:
a) F(2)=0.30
b)P(X>3)=0.7
c)P(2≤X≤5)=0.67
d)P(2<X<5)=0.71
Step-by-step explanation:
a) F(2)=P(X≤2)=0.30
F(2) is given in the probability distribution
b) P(X>3)=1-P(X≤2)=1-F(2)=1-0.3=0.7
P(X>3)=0.7
c)P(2≤X≤5)=?
As we know that P(a≤X≤b)=F(b)-F(a)=P(X≤b)-P(X≤a)
So,
P(2≤X≤5)=P(X≤5)-P(X≤2)=F(5)-F(2)=0.97-0.3=0.67
P(2≤X≤5)=0.67
d)P(2<X<5)=P(1≤X≤4)=P(X≤4)-P(X≤1)=F(4)-F(1)=0.91-0.2=0.71.
P(2<X<5)=0.71
