Question

You have a set of 10 cards numbered 1 to 10. You choose a card at random. Event A is

choosing a number less than 8. Event B is choosing an even number. Calculate the
probability of A NB.
P(A NB) =

Answer 1

35% or 35/100

Explanation:

Gage Millar, Algebra 2 tutor

Choosing a number LESS than (not equal to 8) is 7/10 (1,2,3,4,5,6,7)

Chosing an even number is 5/10 (2,4,6,8,10)

so just multiply 7/10 x 5/10 to get 35 over 100, or a 35% chance
