Answer 1

Answer:

so E = {3}. The sample space S is given by S = {1,2,3,4,5,6}. The number of possible outcomes in E is 1 and the number of possible outcomes in S is 6. ... Hence the probability of getting an even number is P(E) = 3 / 6 = 1 / 2.

Explanation:

hope it works..❤️

Answer 2

Answer:

${ \huge \red{P(E) = 1 / 6}}$

Conditional Probability:

${ \huge \pink{P(A | B) = P(A∩B) / P(B)}}$

Bayes Formula:

${ \huge \green{P(A | B) = P(B | A) ⋅ P(A) / P(B)}}$
