A bag contains 24 discs. 8 are red and 16 are blue.
One disc is taken out at random and replaced by two of the other colour.
Another disc is then taken out at random and replaced by two of the other colour.
Another disk is taken out at random
Work out the probability that all three discs are taken out red

Step-by-step explanation:

8/24 are Red

Pick and return 2

Again pick and return 2

Then it is 6/26

Now multiply the results

8/24 × 7/25 × 6/26 = 7/ 325

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
