Answer:
(45 - 25) / 2 × (2 + 3)
Step-by-step explanation:
Given:
45 - 25/2 × 2 + 3
By trials:
(45 - 25) / (2 × 2) + 3
= 20/4 + 3
= 20/7
Another trial:
(45 - 25)/2 × (2 + 3)
= 20/2 × 5
= 20/10
= 2
The parentheses should be inserted like this
(45 - 25) / 2 × (2 + 3)
Answer:
Multiply each number by the little number next to it then add. It will be a huge number.
Step-by-step explanation: Above.
Answer:
1 / 362880
Step-by-step explanation:
There are 9 possible names that could be first.
After that, there are 8 possible names that could be second.
After that, there are 7 possible names that could be third.
So on and so forth.
So the number of permutations is:
9×8×7×6×... = 9! = 362880
The probability of randomly selecting the one order used in the spelling bee is therefore:
P = 1 / 362880
