Answer:
50 pens
Step-by-step explanation:
x= 25 percent of 200
25/100 times X/200
Cross multiply them and you get
100x=5000
X=5000/100
X=50
25 percent of 200 is 50.
Which means they have away 50 pens
Male Female Total
Income over $50,000 485 385 870
Income below $50,000 65 65 130
<span>Total 550 450 1,000
Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87
0.55 x 0.87 = 0.4785
Probability of being male and earning over $50,000: 485/550 = 0.8818
</span><span>C) No, P(being male | the person earns over $50,000) ≠ P(being male)</span><span>
