Question

There are 13 counters in a bowl.

6 of the counters are purple.
Jamie takes at random a counter from the bowl.
Write down the probability that the counter is purple.
There are only red pins and white pins in a box.
A pin is taken at random from the box.
The probability that the pin is red is 0.4
Find the probability that the pin is white.

Answer 1

P (purple) = 6/13

P (white) = 0.6

Answer 2

6/13, 0.6

Explanation:

For the counters problem. The probability of an event is favorable/total, here the favorable is 6 and the total is 13, giving us 6/13.

for the second question, the 100% chance is equal to a porability of 1, so 1 - 0.4 = 0.6, for a red pin.
