So far, they sold 16 lemonades out of
27+16+12+9=64 drinks.
So, 16/64 = 1/4 of the drinks sold so fare was lemonade. That's the expected probability of someone ordering a lemonade for the next drink.
Answer:
17
Step-by-step explanation:
15 sheep
1 leg = 1 foot
1 head = 1 animal
Suppose all the animals are chickens:
50 × 2 = 100
130 - 100 = 30
4 - 2 = 2
30 ÷ 2 = 15
Hence, there are 15 sheep.
