Both of these scenarios are independent probability. We can use the given formula P(A and B) = P(A) * P(B). In other words, we will find the probability for each event and multiply them by each other.
To find the probability for each event, we will divide the wanted outcome by the total number of possible outcomes.
Question 1:
Aswer:
Explanation:
Landing on a vowel:
(A & E)/(A, B, C, D, E) = 2/5
Landing on an even number:
(2 & 4)/(1, 2, 3, 4) = 2/4
Landing on a vowel and an even number:
2/5 * 2/4 = 4/20
Question 2:
Answer:
Explanation:
Landing on C:
(C)/(A, B, C, D, E) = 1/5
Landing on 4:
(4)/(1, 2, 3, 4) = 1/4
Landing on C and 4:
1/5 * 1/4 = 1/20
