For this there is a dotted line going through -2 on the graph and the shading is on the right side of the grid so -2,-1, and every positive number.
Answer:
<u></u>
Explanation:
You can determine the probability of the collector has captured at least two small monsters of the same species is the complent of that all the monsters captured are of different species, i.e. none are of the same species.
The probability than none of the five captured small monsters are of the same species are:
<u>1. Probability than the one monster is of the species One, and the others are not of the species One:</u>
- (1/32) × (31/32) × (30/32) × (29/32) × (28/32)
<u />
<u>2. Probability that the first monster is of the species Two, and the others are not of the species Two:</u>
- (1/32) × (31/32) × (30/32) × (29/32) × (28/32)
<u>3. Probability that the first monster is of the species Three and the others are not of the same species:</u>
- (1/32) × (31/32) × (30/32) × (29/32) × (28/32)
<u>4. Inference</u>
As you see you have to do this 32 times, and then add all the equal 32 probabilities, which is
- 32 × (1/32) × (31/32) × (30/32) × (29/32) × (28/32) = 0.72
That is the probability that none of the five small monsters are of the same species. Then, the probability that at leas two small monsters are of the same species is 1 - 0.72 = 0.28
It is 18/20 and in simplest form it is 9/10.
Steps:
1.You have to add all the shirts, 2+7+11. This is 20, this will become your denominator
2. See what portion is NOT BLACK, the non black at 7 and 11, once you add these it becomes 18. 18 is now your numerator.
3. You now have the fraction 18/20 which you can simplify into 9/10
Hope this helps :)
