Question 1179549: Gerald is thinking of a number from 1 - 10. Let event A = choosing odd numbers and let event B = choosing numbers less than 7. What is the P(A ∩ B) ?
A ∩ B is the set of numbers { 1, 3, 5 }, consisting of 3 numbers.
So, the entire set of events consists of 10 elements;
of them only 3 (exactly 3) are favorable.
The probability is P = = = 0.3 = 30%. ANSWER
