1. Given that e<span>vents A and B are dependent, P(A)=20%, P(BIA)=25%. What is P(A and B)?
P(BIA)=[P(A and B)]/P(A)
it follows then that:
P(A and B)=P(A)*P(BIA)
P(A)=0.2
P(BIA)=0.25
hence
P(A and B)=0.2*0.25=0.05=5%
2. Given that </span><span> P(A) =12%, P(B)=48% and P(A or B)=50%. What is P(A and B)?
P(A or B)=P(A)+P(B)-P(A and B)
but
P(A)=12%, P(B)=48%, P(A and B)=50%
thus
P(A or B)=12%+48%-50%
simplifying the above we obtain:
P(A or B)=60%-50%=10%

Answer:
First we need to turn the values into decimals
2
Step-by-step explanation:
5/8 = 0.625
1/2 = 0.50
1/4 = 0.25
Now add the decimal values up which would be 0.625 + 0.50 + 0.25 = 1.375
You can't have 1.375 of a pizza so joe's dad is going to order at the minimum 2 pizzas so that everyone can have their desired amount
Answer:
No
Step-by-step explanation:
4/20 is a fraction just like 5/20. 5 is higher than 4, which means it'd take less time to get to 20 using five than it would with 4
Answer: well search It up 1/10
Step-by-step explanation:
(1) Using a trapezoidal sum, we approximate the integral by
measured in gallons of water.
(2) Notice that the table shows the specific values of 
increasing, meaning 
. There's not enough evidence to suggest that we have 
at any time.
