Answer:
a) 0.11
b) 60
Step-by-step explanation:
Total frequency:
12+35+11+23+7+12 = 100
P(3) = 11/100 = 0.11
P(6) = 12/100 = 0.12
Expected no. of sixes:
500 × 0.12 = 60
Answer: One possible way: 123 - 45 - 67 + 89
Step-by-step explanation: The goal is to get 100, using all of the following numbers: (1,2,3,4,5,6,7,8,9)
We can merge numbers to get 100.
123 - 45 - 67 + 89 (We used every number once)
Lets solve from left to right.
123 - 45 = 78. 78 - 67 = 11. 11 + 89 = 100.
Answer:
11
Step-by-step explanation:
