There are 26 counters in a bag. 5 of the counters are pink. 10 of the counters are blue. the rest of the counters are white. jan puts some more pink counters into the bag. she then takes some blue counters out of the bag. after she has done this there are still 26 counters in the bag. jan then takes at random a counter from the bag. the probability that she takes a pink counter is 1/2 what is the probability that she takes a blue counter?

Respuesta :

The probability of picking a blue counter from the bag is 1 / 13.

What is the probability?

The number of counters initially in the bag:

  • white counters = 26 - 10 - 5 = 11
  • pink counters = 5
  • blue counters = 10

The number of counters now in the bag:

  • white counters = 11
  • pink counters = (5 + x) / 26 = 1/2

13/26

x = 13 - 5 = 8

  • blue counters = 26 - 13 - 11 = 2

Probability of picking a blue counter = number of blue counters / total number of counters

2/26 = 1 / 13
