Step-by-step explanation:
Before we begin answering, we need to go over the rules of multiplying polynomials.
Unlike in regular multiplication, we have to combine the like terms in the subtracting portion of the multiplication process.
Another rule is that when there are more than 1 variable in a term, we need to take the variables as two separate variables and then proceed to multiply them.
Answer:
0.24
Step-by-step explanation:
These events are not mutually exclusive; this means they can happen at the same time.
For two events A and B that are not mutually exclusive,
P(A and B) = P(A) * P(B|A)
Let A be the event "over 21 years old" and B be the event "drinks alcohol".
The probability that a student is over 21 years old is 0.3; this is because 30% of the students are over 21 years old.
The probability that a student drinks alcohol given they are over 21 is 0.8.
This gives us
P(A and B) = 0.3(0.8) = 0.24
Answer:( 1) 1/5 , 0.2 , 20%
(2) 2/5, 0.4 , 40%
Step-by-step explanation:
Answer:11:10
Step-by-step explanation:
7 hours plus 3 hours is 10
And 40 mins plus 30 is 1 hour 10 mins
