Answer:
About 41.5%
Step-by-step explanation:
<em>Given:</em>
<em>A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. </em>
<em>To Find:</em>
<em>What is the probability that both grapes are red?</em>
<em>Answer choices:</em>
<em>about 39.7% </em>
<em>about 41.5%</em>
<em> about 42.5% </em>
<em>about 44.5%</em>
<em>Solution:</em>
<em>Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 . </em>
<em>As the red grapes are 15.. </em>
<em>Thus, </em>
<em>The probability of choosing a red grape the first time is 15/23.</em>
<em>Because out of the total 23 grapes only 15 were red grape.</em>
<em> The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice</em>
<em>Hence, the probability of choosing or eating two red grapes will be :</em>
<em>15/23×14/22 </em>
<em>=105/253 </em>
<em>=0.415</em>
<em>= 41.5% </em>
<em>Therefore, the probability that both grapes are red is about 41.5%</em>

I think the awnser is 30 becuase 27 and 3 left add them and that is what i got
Answer:
6.8%
Step-by-step explanation:
the question has no information about class size (no. of student in class)
assume no. of student is infinite
P(3brown out of 6) = 6C3 * P(brown)^3 * P(not brown)^3
= 20 * 0.004913 * 0.695789
= 0.06837
Answer:
5:1
Step-by-step explanation:
Divide each by 3.
f(x) = 6x - 12
y = 6x - 12
y + 12 = 6x - 12 + 12
<u>y + 12</u> = <u>6x</u>
6 6
¹/₆y + 2 = x
y = ¹/₆x + 2
f⁻¹(x) = ¹/₆x + 2
f⁻¹(-3) = ¹/₆(-3) + 2
f⁻¹(-3) = -¹/₂ + 2
f⁻¹(-3) = 1¹/₂
(x, f⁻¹(x)) = (-3, 1¹/₂)
