In Q. No. 1, The probability that the digit is even is
पर्याय
\[\frac{4}{9}\]
\[\frac{5}{9}\]
\[\frac{1}{9}\]
\[\frac{2}{3}\]
उत्तर
digits are chosen from 1, 2, 3, 4, 5, 6, 7, 8, 9 are placed in a box and mixed thoroughly. One digit is picked at random.
TO FIND: Probability of getting an even digit
Total number of digits is 9
Digits that are even number are 2, 4, 6, and 8
Total number of even digits is 4.
`"We know that PROBABILITY "= "Number of favourable event" /"Total number of event"`
Hence probability of getting an even digit is `4/9`

A card is drawn at random from a pack of well shuffled 52 playing cards. Complete the following activity to find the probability that the card drawn is:
Event A: The card drawn is an ace.
Event B: The card drawn is a spade.
Activity: 'S' is the sample space.
∴ n(S) = 52
Event A: The card drawn is an ace.
∴ n(A) = `square`
P(A) = `square` ......(formula)
∴ P(A) = `square/52`
∴ P(A) = `square/13`
Event B: The card drawn is a spade.
∴ n(B) = `square`
P(B) = `(n(B))/(n(S))`
∴ P(B) = `square/4`
