Answer:
Gareth has a deck of cards with 12 challenge cards and 8 prize cards.
=> The probability he selects a prize card: P = 8/(12 + 8) = 8/20 = 0.4
Gareth is going to randomly select a card from the deck 148 times, replacing the card and shuffling the deck after each selection .
=>The randomness is kept same for all selecting times
Then the best prediction for the number of times Gareth will select a prize card:
=> N = 0.4 x 148 = 59.2 = 59 times
Hope this helps!
