Find the number of outcomes in the complement of the given event. Out of 243 high school students in their junior year, 139 are right-handed.

94

Step-by-step explanation:

Let the universal set be U. n(U) = 243

let the right handed high school students in their junior year be R. n(R) = 139

Complement of the given event refers to the left-handed people. Therefore, number of outcomes in the complement of right handed people, n(R') = n(U) - n(R) = 243 - 139 = 94. Hence, the required answer is 94.
