Answer:
0.18% probability that they are all women
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the senators are chosen is not important, so the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
3 women, from a set of 13. So
Total outcomes:
3 senators, from a set of 100. So
Probability;
0.18% probability that they are all women
1. 5x/2 +y=-3
2. False
3. y= -5x-37 because y=mx-b
4. y= 1/5 x - 1 because y=mx-b
M= the slope and b represents the intercept.
It’s 1 be the same one ☝️ and I don’t think can be in here lol
Answer:
a) and b) in photo.
there is no point left outside the circles, then 11+15 is even.
c) yes it is, because if both numbers are odd, they will have one point outside the circles each, and those two points will form an other pair.
odd number: 2n+1
even number: 2m
(m and n represent any natural number)
2n+1 + 2k+1= <em>the sum of two odd numbers</em>
=2(n+k) +2
=2(n+k) +2 =2(n+k+1)
<em>the sum of 3 natural numbers will be a natural number too. let be m=n+k+1 with m n and k natural numbers.</em>
=2m <em>even number</em>
