There are five different colored cards in a hat (red blue green yellow and black) a card is randomly drawn and replaced then a second card is drawn what is the probability that the first card will be red and the second card will be blue

Step-by-step explanation:

the probability that the first card will be red and the second card will be blue:

p(red then blue) = p(red) × p(blue)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
