Question

A bag contains 15 cards numbered 1to15 fond the probability of drawing a card from the bag randomly (a) card has a number multiple of 3

Answer 1

Answer:

Probability of getting a prime number=6/15=2/5

probability of getting a number divisible by 2= 7/15 ✓✓

Answer 2

Answer:

The probability of drawing a card from the bag randomly that has a number multiple of 3 is 0.2667.

Step-by-step explanation:

The cards in the bag are numbered 1 to 15.

Total number of outcomes, N = 15.

The multiple of 3 in this range are: {3, 6, 9, 12}

Favorable outcomes, n = 4.

The probability of an event E is:

$P (E)=\frac{Favorable\ Outcomes}{Total\ number\ of\ outcomes}$

Compute the probability of selecting a card that has a number which is a multiple of 3 as follows:

$P (Multiple\ of\ 3)=\frac{n}{N}=\frac{4}{15} =0.2667$

Thus, the probability of drawing a card from the bag randomly that has a number multiple of 3 is 0.2667.
