Question

A bag contains cards numbered from 1 to 50. A card is drawn at random from the bag. The probability that the number on this card is divisible by both 3 and 4 is

Answer 1

Step-by-step explanation:

Let E be the event of drawing an odd-numbered card from the cards numbered 1 to 49

Odd numbers from 1 to 49=1,3,5,.....,49

No. of favorable outcomes=25

Total no. of possible outcomes =49

We know that, Probability P(E) =

(Total no.of possible outcomes)

(No.of favorable outcomes)

=

49

25

Therefore, the probability of an odd number card from the cards numbered 1 to

Answer 2

Answer:

The numbers 3 and 4 are co-prime numbers  as they do have have any factors common except 1,

so the multiples of 12 [∵3×4=12] are the only common multiples of 3 and 4

multiples of 12 less than 50 ⇒12,24,36,48⇒4 outcomes

P[e]=no.of favorable outcomes/total no.of outcomes

P[getting a multiple divisible by both 3 and 4]=4/50

ANSWER:⇒4/50 or 0.08
