There are 5 marbles in a bag: 4 are blue, and 1 is red. What is the probability that a blue marble gets picked?
Let me see.
Let E = selecting a blue marble
Let P(E) = probability of selecting a blue marble
P(E) = (what we want to take place)/(the total number of marbles in a bag)
P(E) = 4/5
Question:
All probabilities are between 0 and 1. This means that probabilities are decimals and/or fractions.
Yes?
