The probability of pulling a red or green card, written as a reduced fraction is 1/4

<h3>How to determine the probability of pulling a red or green card, written as a reduced fraction?</h3>

From the question, we have the following probabilities:

P(White) = 1/10

P(Pink) = 1/5

P(Green) = 1/20

P(Red) = 1/5

The probability of pulling a red or green card, written as a reduced fraction is the calculated as:

P(Red or Green card) = P(Red card) + P(Green card)

Substitute the known values in the above equation

P(Red or Green card) = 1/5 + 1/20

Express 1/5 as 4/20

P(Red or Green card) = 4/20 + 1/20

Take the LCM

P(Red or Green card) = (4+1)/20

Evaluate the sum

P(Red or Green card) = 5/20

Simplify the fraction

P(Red or Green card) = 1/4

Hence, the probability of pulling a red or green card, written as a reduced fraction is 1/4

brandon wants to join a video game club. The membership costs $47, and every game that he rents will cost $2.if brandon rents 17
Slav-nsk [51]
If you add $47 to $17 multiplied by two, then the total cost would be $81 because 17 multiplied by two is 34, and 47 added to 34 is 81, so the total amount paid would be $81.
