Question

Find the probability of drawing an ace from a deck of cards

Answer 1

Answer:

TOTAL CARDS = 52

NO. OF ACE'S = 4

PROBABLITY = $\frac{NO. OF FAVOURABLE OUTCOMES}{TOTAL NUMBER OF OUTCOMES}$

=$\frac{4}{52}$

= $\frac{1}{13}$

Step-by-step explanation:

According to the Question

Let the ratio be 5x : 4x

Total number of people in group = 72

We need to calculate the number of lawyers in the group & it is also given that the ratio of doctor to lawyers is 5:4

Sun of Ratios = Total number of people

Substitute the value we get

:\implies:⟹ 5x + 4x = 72

:\implies:⟹ 9x = 72

:\implies:⟹ x = 72/9

:\implies:⟹ x = 8

Now, putting the value of x = 8

4x = 4×8 = 32

Hence, the number of lawyers in the group is 32 .

Answer 2

" The probability of picking up an ace in a 52 deck of cards is 4/52 since there are 4 aces in the deck. The odds of picking up any other card is therefore 52/52 - 4/52 = 48/52.
