Question

The probability of drawing an even number or number greater than 4 containing the numbers 1-10, inclusive.

Answer 1

Key word here, "or"...so you would add the unique probabilities of either together...

P(e)=1/2, P(>4)=3/10  (the numerator is three rather than five because 2 and 4 were already accounted for in P(e)...

P=5/10+3/10=8/10=4/5  (80%)

P=0.8
