In this lesson, we will learn how to find the probability of the difference of two events.
Students will be able to
Q1:
Suppose that 𝐴 and 𝐵 are two events. Given that 𝑃(𝐴−𝐵)=27 and 𝑃(𝐴∩𝐵)=16, determine 𝑃(𝐴).
Q2:
Suppose 𝐴 and 𝐵 are two events. Given that 𝑃(𝐴)=0.3 and 𝑃(𝐴∩𝐵)=0.03, determine 𝑃(𝐴−𝐵).
Q3:
A ball is drawn at random from a bag containing 12 balls each with a unique number from 1 to 12. Suppose 𝐴 is the event of drawing an odd number and 𝐵 is the event of drawing a prime number. Find 𝑃(𝐴−𝐵).
