Question

what are the probability of the following events?.. to draw from a well - shuffled deck of 52 playing cards (a) a red card (b) an ace... 2) go throw a box containing 60 non - defective and 40 defective bulb, to take (a) non defective bulb (b) defective bulb.

Answer 1

26/52 first ka answer and second ka 4/52

Answer 2

1 answer )

Total number of cards = 52

Number of all possible out comes in selecting a card at random = 52

a) red colour

number of favorable outcomes = 26
no.of total outcomes = 52
probability of getting a red colour = 26/52

b) an ace

no.of favorable outcomes = 4
no.of total outcomes = 52
probability to get an ace = 4/52



2 answer )


In a box defective and non-defective bulbs are there

Total no.of bulbs = 60+40 = 100

a) non-defective bulb

no.of favourable outcomes = 60
no.of total outcomes = 100
probability of getting non-defective bulb = 60/100


b) defective bulb

no.of favourable outcomes = 40
no.of total outcomes = 100
probability of getting defective bulbs = 40/100
