Question

Suppose you ask a friend to randomly choose an integer between 1 and 10, inclusive.What is the probability that the number will be more than 4 or odd? (Enter your probability as a fraction.)

Answer 1

we know that

total outcomes=10

favorable outcomes

more than 4 -------> 5,6,7,8,9,10

odd numbers -----> 1,3,5,7,9

so

more than 4 or odd numbers=1,3,5,6,7,8,9,10-------> total=8 numbers

therefore

The probability is

P=8/10

simplify

P=4/5
