Answer:
<u>NOT BOTH BLACK = 1-2/25 = 23/25</u>
Step-by-step explanation:
Bag 1 : 8 non-black out of 10
P(1) = 8/10
Bag 2: 3 non-black out of 10
P(2)=3/5
Probability of both independent events happening can be calculated using the multiplication rule
P(1) and P(2) = P(1)*P(2) = 8/10 * 3/5 = 24/50 = <u>12/25 (both are not black, or none is black)</u>
Interpretating not both black meaning at most one black, then
we calculate the probability of both are black,
P(1) = 2/10
P(2) = 2/5
Probability that both balls are black can be calculated using the multiplication rule
P(1) and P(2) = 2/10 * 2/5 = 2/25
Probability that <u>NOT BOTH BLACK = 1-2/25 = 23/25, i.e. at most one black</u>
Answer:
- Given and Explained Below.
Step-by-step explanation:
slope intercept form: y = mx + b ............where m is slope and b is y-intercept
<u>1st question:</u>
4x + y = 1
y = 1 - 4x
y = -4x + 1
<u>2nd question:</u>
x + 2y = 9
2y = 9 -x
y = (-x + 9)/2
y =

3.)77
Step-by-step explanation:
Given:
The number of tickets = 1000
Mathew buys a single ticket for $8
Winning price = $800
To find:
The expected earning per ticket.
Solution:
It is given that the total number of tickets is 1000. So, the probability of winning is:

The probability of losing is:

The expected earning per ticket is:






Therefore, the expected earning per ticket is -7.192. Here, negative sign means loss of $7.192.
