Answer: 0.2224
Step-by-step explanation:
Given: The proportion of adults need eye correction: p= 78%=0.78
Let X be a binomial variable that represents the number of adults who need eye correction.
Sample size of adults: n= 12
Binomial ditsribution formula:
Now, the probability that at least 11 of them need correction for their eyesight will be
Hence, the required probability = 0.2224
Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).
Step-by-step explanation:
Given
Required
Reasonable first step
The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.
This gives:
<em>Then the solution can be continued</em>
The answer would be 15/21
