A box contains 100 red cards,200 yelow cards and 50 blue cards if a card is drawn at randomb from the box,then find the probability that it will be not a yellow card
Answers
Answer:
Step-by-step explanation:
SOLUTION :
GIVEN : Number of red cards = 100
Number of yellow cards = 200
Number of blue cards = 50
Total number of cards in a box = 100 + 200 + 50 = 350
Total number of outcomes = 350
(i) Let E1 = Event of selecting that a card drawn is blue
Number of blue cards = 50
Number of outcome favourable to E1 = 50
Probability (E1) = Number of favourable outcomes / Total number of outcomes
P(E1) = 50/350 = 1/7
Hence, the required probability of getting a card drawn is blue, P(E1) = 1/7
(ii) Let E2 = Event of selecting that a card drawn is not a yellow card
Number of cards which are not yellow = 100 + 50 = 150
Number of outcome favourable to E2 = 150
Probability (E2) = Number of favourable outcomes / Total number of outcomes
P(E2) = 150/350 = 15/35 = 3/7
Hence, the required probability of getting a card drawn is not a yellow card , P(E2) = 3/7
(iii) Let E3 = Event of selecting that a card drawn is neither yellow nor blue
Number of cards which are neither yellow nor blue = 100
Number of outcome favourable to E3 = 100
Probability (E3) = Number of favourable outcomes / Total number of outcomes
P(E2) = 100/350 = 10/35 = 2/7
Hence, the required probability of getting a card drawn is neither yellow nor blue , P(E3) = 2/7
