Question

a. in a bouquet of 25 flowers there are roses and tulips if there are 13 roses what is the ratio of roses to tulips

b. If shop A sells 338 TVs and shop B sells 508 TVs find the ratio of TVs sold at shop A to TVs sold at shop B

c. if from a shuffled deck of 52 cards a card is drawn and it is seven of hearts, then another card is drawn find the probability that the 2nd card drawn is an eight of hearts

Answer 1

1) Given, in a bouquet of 25 flowers there are 13 roses and some tulips.

Then, the number of tulip flower is = (25-13) = 12

Now, the ratio of roses to tulips is = 13:12.

b) Given that shop A sells 338 TVs and shop B sells 508 TVs.

Then, the ratio of TVs sold at shop A to TVs sold at shop B is = 338:508

Dividing both of 338 and 508 by 2 we get = 169:254

Therefore, the required ratio is = 169:254.

c) After drawing the 'seven of hearts' card from a shuffled deck of 52 cards, the number of remaining cards is = 51.

Now, the probability that the 2nd card drawn is an eight of hearts is = 1/51.
