Question

1. From a well shuffled pack of cards, a card is drawn at random. Find the probability of getting a black queen.
2. Find the probability of getting 53 sundays in a non leap year. ​

Answer 1

Answer:

1. Step-by-step explanation:

No. of cards = 52. No. of black queens = 2. So, Probability of black queen = 2/52 = 1/26.

2. 1 remaining day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. Total of 7 outcomes, the favourable outcome is 1. ∴ probability of getting 53 Sundays = 1 / 7.

Answer 2

→Solution

1.

Number of black queens in a pack of cards =2

∴ P (black queen) = 2/52

= 1 /26

→Answer : The probability of getting a black queen is 1 /26.

2.

1 Remaining day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday.

→Total of 7 outcomes, the favourable outcome is 1.

∴ Probability of getting 53 Sundays = 1 / 7.

→Answer : 1 /7 is the getting 53 Sunday in non leap year.
