The answer to this problem is 45
Answer:
Hey there!
This is because the theoretical probability is different from the experimental probability. The theoretical probability is what is expected, but the experimental probability is what actually happens.
Hope this helps :)

Step-by-step explanation:
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
5 pounds of bananas cost 0.80*5 = 4 dollars
5 pounds of apples cost 1.40 *5 = 7 dollars
4+7 = 11 dollars
11 dollars is greater than 10 so she does not have enough and needs 1 more dollar
