Answer: 40 times.
Step-by-step explanation:
If the probability in a sigle spin of getting the colour pink is p = 0.2
This means that in 0.2*100% = 20% of the spins we should see the colour pink.
Then, out of 200 spins, the 20% of 200 is
(20%/100%)*200 = 0.2*200 = 40
This means that out of 200 spins, in around 40 of them we will se the colour pink.
If the rate at which they are giving the DVDs is the same then it is 4/65 or 16.25% or 0.1625.
Now just multiply 455 by the rate (4/65 or 16.25% or 0.1625) to find how many DVDs were given.
455 × (4/65) = 28
28 DVDs were given away
