Answer:
Let X be the event of feeling secure after saving $50,000,
Given,
The probability of feeling secure after saving $50,000, p = 40 % = 0.4,
So, the probability of not feeling secure after saving $50,000, q = 1 - p = 0.6,
Since, the binomial distribution formula,
Where, 
If 8 households choose randomly,
That is, n = 8
(a) the probability of the number that say they would feel secure is exactly 5
(b) the probability of the number that say they would feel secure is more than five
(c) the probability of the number that say they would feel secure is at most five
Answer:
a. 19
b. 14
Step-by-step explanation:
From the venn diagram, we see that:
9 children like only Vanilla
7 like vanilla and chocolate
12 like only chocolate, and
2 like neither chocolate nor vanilla
Thus:
a. Number of children that liked Chocolate ice-cream = those that like chocolate only + those that like both chocolate and vanilla = 12 + 7 = 19
19 children like chocolate ice-cream.
b. Number of children who do not like Vanilla ice-cream = those that like chocolate only + those that do not like neither chocolate nor vanilla = 12 + 2 = 14
14 children do not like vanilla ice-cream.
it should be 16.5 because the other chord, half of it is 8.25. good luck!
Answer:
$66.50
Step-by-step explanation:
Given that
she bought seven 1.45 rolls
Three 7.60 sweet loaves
and four 8.40 sweet rolls
We need to find out how much she paid in total
So,
= 7 × 1.45 + 3 × 7.60 + 4 × 8.40
= $10.15 + $22.80 + $33.60
= $66.50
Hence, she paid in total of $66.50
The same would be considered and relevant
