Probability (Set 2) Worksheet

Sample problems

Find each probability as a fraction in lowest terms (or as told). Recall that probability is between $0$ and $1$, and that $P(\text{not }A)=1-P(A)$.

1. 1. The spinner shown has $6$ equal sections numbered $1$ through $6$. What is the probability of landing on the section numbered $2$?
2. 2. A bag holds $4$ red, $6$ yellow, and $2$ green marbles. If one marble is drawn at random, find $P(\text{yellow})$.
3. 3. Using the bag from the previous problem ($4$ red, $6$ yellow, $2$ green), find $P(\text{not yellow})$ using the complement.
4. 4. A standard number cube (faces $1$ through $6$) is rolled once. Find $P(\text{rolling a number less than }3)$.
