Name: ___________________________________________________ Date: ______________ d) Using the information in the table, what is P(red or blue, 4)? Write your answer as a fraction. Die Spinner 1 2 3 4 Blue (B) B, 1 B, 2 B, 3 B, 4 Red (R) R, 1 R, 2 R, 3 R, 4 Yellow(Y) Y, 1 Y, 2 Y, 3 Y, 4 Solution In the table, circle (R, 4) and (B, 4). P(R or B, 4) = favourable outcomes possible outcomes = 12 e) Use multiplication to check your answer in part d). Solution yellow red blue 3 4 P (R or B) = favourable outcomes possible outcomes P (4) = favourable outcomes possible outcomes = 3 = 4 Multiply the probabilities of the 2 events. P(R or B) × P(4) = 3 × 4 = 12 612 MHR ● Chapter 11: Probability
Name: _____________________________________________________ Date: ______________ You roll a 4-sided die and spin the spinner. Find the probability of rolling a number less than 4 and spinning A. Check your answer using multiplication. Complete the table. 2 3 B A Die Spinner 1 2 3 4 A B favourable outcomes P (number less than 4 and A) = possible outcomes = Check using multiplication. 2 3 A B favourable outcomes P (number less than 4) = possible outcomes P (A) = favourable outcomes possible outcomes = 4 = 2 P(number less than 4) × P(A) = × = 11.3 Determining Probabilities Using Fractions ● MHR 613
