Answer:
1.10
Step-by-step explanation:
Given the probability distribution :
x : ___ 0 ___ 1 ___ 2
p(x)__0.15 _0.60 __0.25
The expected value is obtained by:
Σ(X * p(x))
(0 * 0.15) + (1 * 0.60) + (2 * 0.25)
0 + 0.60 + 0.50
= 1.10
Answer:
Mr Batista should bring more 82 cups.
Step-by-step explanation:
- there are 36 cups in 1 package.
- for 12 packages: [ 12 * 36 ] = 432 cups - this many cups he brought.
solve:
→ 514 - 36(12)
→ 514 - 432
→ 82
He needs more 82 cups and did not bring enough.
