Answer:
Step-by-step explanation:
9(9m+3t) = 9 *9m + 9*3t
= 81m + 27t
Answer:
(3, 6)
Step-by-step explanation:
(x1, y1) and (x2, y2)
x2 - x1, y2 - y1
(x*, x*)
(2, 1) and (5, 7)
5 - 2, 7 - 1
(3, 6)
1. P(getting all head)=
![\frac{n(getting-all-head)}{n(Sample-space)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%28getting-all-head%29%7D%7Bn%28Sample-space%29%7D%20)
2. Event: getting all head can happen in only one way: HHH
3. n(Sample space) can be calculated by
a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE
or
b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.
4. So finally P(getting all head)=
Answer:
the second one -(1/4)^3
Step-by-step explanation:
-(1/4)^3
= -(1^3/4^3)
= -1/64
