A number cube is tossed and one card is randomly drawn. Find P(3, yellow) (BTW There are 5 cards 3 yellow 2 blue) The answer choice are: A. 1/30 B. 1/25 C.3/25 D.1/10

Respuesta :

i believe its 1/10 because there are 10 cards 

Answer: [tex]\dfrac{1}{10}[/tex]

Step-by-step explanation:

Probability =[tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Given : A number cube is tossed and one card is randomly drawn.

Total outcomes for cube = 6

Total outcomes fro cards = 5

Number of yellow cards = 3

Event 1 : drawing 3 on cube .

[tex]P(E_1)=\dfrac{1}{6}[/tex]

Event 2 : drawing a yellow card .

[tex]P(E_2)=\dfrac{3}{5}[/tex]

Since both events are independent then probability of getting  3 on cube and a yellow card is [tex]P(E_1)\times P(E_2)[/tex]

i.e. [tex]\text{P(3, yellow)}=\dfrac{1}{6}\times\dfrac{3}{5}=\dfrac{1}{10}[/tex]

Hence, P(3, yellow)= [tex]\dfrac{1}{10}[/tex]
