Question

A one card is drawn from well shuffled 52 cards find the probability getting 1.heart 2.king or queen 3. red colour

Answer 1

Answer:

1.) 1/4

2.) 2/13

3.) 1/2

Step-by-step explanation:

No.of all possible outcomes=52

1.) Let R be event of 'getting a heart cards'

there are 13 cards of a heart

No. of outcomes favourable to 'event R' =13

P(R)=no.of outcomes favourable to event R

÷no.of all possible outcomes

• P(R)=52÷13=1/4

2). Let T be event of 'getting a king or queen'

there are 8 cards of a king or queen

No.of outcomes favourable to 'event T'=8

P(T)=no.of outcomes favourable to event R

÷no.of all possible outcomes

• P(T)=52÷8=2/13

3.) Let E be event of 'getting a red card'

there are 26 cards of a red card

No.of outcomes favourable to 'event E'=26

P(T)=no.of outcomes favourable to event R

÷no.of all possible outcomes

• P(T)=52÷26=1/2
