Question

Jose is playing cards with his friend when he draws a card from a
pack of 40 cards numbered from 1 to 40. What is the probability
of drawing a number that is a square?​

Answer 1

Answer:

6/40

Step-by-step explanation:

There will be 7 square numbers among the pack of cards which are 1,4,9,16,25,36,49

Answer 2

Step-by-step explanation:

Given:-

Jose is playing cards with his friend when he draws a card from a pack of 40 cards numbered from 1 to 40.

To find:-

What is the probability of drawing a number that is a square?

Solution:-

Total number of playing cards in a deck of cards = 40

Total number of possible outcomes = 40

The numbers are : 1,2,3,4,...,40

The square numbers = 1,4,9,16,25,36.

Sample space for square numbers

= {1,4,9,16,25,36}

Number of favourable outcomes = 6

We know that

Probability of an event P(E) =

Number of favourable outcomes/Total number of all possible outcomes

Probability of getting a square number

= 6/40

= 3/20

Answer:-

Probability of getting a square number is 3/20

Used formulae:-

Probability of an event P(E) =

Number of favourable outcomes/Total number of all possible outcomes
