 In an athletic competition, the probability that an athlete wins a 100m race is 1/8 and the probability that an athlete wins a 100m race is 1/8 and the probability that he wins in high jump is 1/4. What is the probability that he wins only one of the events? The Pr. Of winning only one event means it's either he win the 100m race OR the high jump. Rem. OR in probability means addition. 1/8 * (1 - 1/4) + 1/4 * (1 - 1/8) = 1/8 * 3/4 + 1/4 * 7/8 = 3/32 + 7/32 = 10/32 To the Lowest term: Ans = 5/16 Submit a question or another method of solving the above question in the comment section Visit myschool for more solutions Follow Fiero Academy on Instagram

The Probability that Musa passes English, Mathematics and Geography are 1/3, 2/5, and 3/4 respectively. What is the probability of passing all?

  The Probability that Musa passes English, Mathematics and Geography are 1/3, 2/5, and 3/4 respectively. What is the probability of passing all? Probability of passing all = Pr(Eng) and Pr(Maths) and Pr(Geog) Remember "and" means multiplication Therefore Pr(all) = 1/3 * 2/5 * 3/4 Ans = 1/10

A basket contains 50 eggs, 15 of them are bad. If the egg is taken out, find the probability that it is good.

  A basket contains 50 eggs, 15 of them are bad. If the egg is taken out, find the probability that it is good. Good eggs = 50 - 15/50  = 35/50  Breaking it down we have: Ans: 7/10
