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

Verified Answer :

i believe its 1/10 because there are 10 cards

Answer: \(\dfrac{1}{10}\)

Step-by-step explanation:

Probability =\(\dfrac{\text{favorable outcomes}}{\text{total outcomes}}\)

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 .

\(P(E_1)=\dfrac{1}{6}\)

Event 2 : drawing a yellow card .

\(P(E_2)=\dfrac{3}{5}\)

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

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

Hence, P(3, yellow)= \(\dfrac{1}{10}\)
