A bottle of water - 60p
A bag of crisp - 85p
Answer:
£6.50, John is incorrect
Step-by-step explanation:
Number of working days = 5 = number of days meal is purchased
Total cost per meal, shop A :
£(2.85 + 0.60 + 0.85) = £4.3
Total cost for the week = 4.3 * 5 = £21.50
Total cost per meal cost Shop B = £3
Total cost for the week = 3 * 5 = £15
Difference :
£21.50 - £15 = £6.50
Hence, Amount John saves by buying from shop B is £6.50
Numbe
There are 52 cards in a deck, half the cards aware red and half the cards are red.
First card being red is 26/52 = 1/2
After the first card is dealt there are 51 cards left and 26 are black so dealing a black card = 26/51
After 2 cards are dealt there are 50 cards left and 25 red ones left. The probability would be 25/50 = 1/2
The probability of all 3 happening = 1/2 x 26/51 x 1/2 = 13/102
Answer: 13/102
