Probability that the outcome was less than three or even = 5/6
Step-by-step explanation:
The sample outcome of a six siddded die = {1, 2, 3, 4, 5, 6}
Total number in the sample = 6
Numbers less than 3 = {1, 2}
probability of getting number less than 3 = total numbers less than 3/Total number in the sample
total numbers less than 3 = 2
probability of getting number less than 3 = 2/6
Numbers that are even = {2, 4, 6}
probability of getting even number = total numbers that are even/Total number in the sample
total numbers that are even = 3
probability of getting even number = 3/6
Probability that the outcome was less than three or even = probability of getting number less than 3 + probability of getting even number
Probability that the outcome was less than three or even = 2/6 + 3/6 = (2+3)/6
Probability that the outcome was less than three or even = 5/6
