Answer: Probability that a student is absent given that today is Monday is 0.15.

Step-by-step explanation:

Since we have given that

Probability that it is Monday and that a student is absent P(M∩A) = \dfrac{3}{100}

Number of school days in a week = 5

Probability that a randomly selected day of the school week is Monday = P(M)=\dfrac{1}{5}

We need to find the probability that a student is absent given that today is Monday.

We will use "Conditional Probability":

P(A|M)=\dfrac{P(M\cap A)}{P(M)}\\\\P(A|M)=\dfrac{0.03}{0.2}\\\\P(A|M)=0.15

Hence, Probability that a student is absent given that today is Monday is 0.15.

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea
Liono4ka [1.6K]

Answer:

30 gallons

Step-by-step explanation:

step 1 right it out

2 hour is 120 mins and 4 cups are poured per min

step 2 Equation time

so your equation should be

4/1=x/120

step 3 solve it out

1 times 120 is 120 is 4 times 120 is 480

but that is not the answer 480 is the amount of CUPS that are used for 2 hrs

so all u have to do is now convert

step 4 convert

16 cups are in 1 gal. so divide 480 by 16 and get 30 gal

x=30 gallons

hoped it helped
