Answer:
8/9
Step-by-step explanation:
1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles = 18 marbles
The number that are not yellow = total - yellow
P( not yellow) = number that are not yellow / total
= (18-2) / 18
= 16/18
=8/9
Answer:
(2, 2) states x=2 and y=2
Considering the inequality:
Is y less than or equal to 2 when x = 2?
Yes, (2, 2) is a solution for the inequality.
The probability that either the girls' or boys' team gets a game is 0.85
Step-by-step explanation:
Step 1:
Let P(G) represent the probability of girls team getting a game and P(B) represent the probability of the boys team getting a game.
P(B ∪ G) represents the probability of either girls and boys team getting a game.
P(B ∩ G) represents the probability of both girls and boys team getting a game.
Step 2:
It is given that P(G) = 0.8, P(B) = 0.7 and P(B ∩ G) = 0.65
We need to find the probability of either girls or boys team getting a game which is represented by P(B ∪ G)
Step 3:
P(B ∪ G) = P(B) + P(G) - P(B ∩ G)
= 0.8 + 0.7 - 0.65 = 0.85
Step 4:
Answer:
The probability that either the girls' or boys' team gets a game is 0.85
Answer:
Step-by-step explanation:
Given:
A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint.
Question asked:
How many pints of yellow paint will be needed if the mixture contains one pint of blue paint ?
Solution:
We will easily find quantity of yellow paint, will be needed in the mixture, contains one pint of blue paint by using unitary method:
By using 
blue paint, yellow paint requires = 
By using 1 pint blue paint, yellow paint requires = 
Thus, pint yellow paint requires in the mixture with one pint of blue paint.
