Question

18. What is the probability of drawing a BLACK card with an odd number OR a card with a LETTER?A.21261B..ع1726p D. 13

Answer 1

Let:

A = Draw a black card

B = Draw and odd number

C = Draw a card with a letter

so:

`\begin{gathered} P(A\cap B)=(8)/(52)=(2)/(13) \\ P(C)=(16)/(52)=(4)/(13) \end{gathered}`

Therefore:

`P((A\cap B)\cup C)=(2)/(13)+(4)/(13)=(2+4)/(13)=(6)/(13)`
