Answer:
15 (50*0.3)
Step-by-step explanation:
First, we must count the amount of tiles.
Amount = 2 + 6 + 4
A = 12 tiles
Then let's to the Example 18:
P(X then Y) = P(x) × P(y)
We have 2 lites x
P( x then y) = 2 / 12 × P(y)
We have 6 lites y
And as one lites X was choosed:
P(y) = 4 / 11
P(x then y) = (2/12) × ( 4 /11)
= 6.06%
____________________
Example 19:
P(both y) = P(y)' × P(y)
We have 4 lites y
P(y)' = 4/12
Now us have 3 lites y
P(y) = 3 / 11
P(both y) = (4/12)×(3/11)
= 9.09%
_________________
Example 20:
P(y then x) = P(y) × P(x)
We have 4 lites y
P(y) = 4 /12
Now us have 11 lites on the bag
P(x) = 2 / 11
P(y then x) = (4/12)×(2/11)
= 6.06%
___________________
Example 21:
P(z then x) = P(z) × P(x)
We have 6 lites z
P(z) = 6 / 12
Now us have 11 on the bag
P(x) = 2/11
P(z then x ) = (6/12)×(2/11)
= 9.09%
___________________
Example 22:
P(both z) = P(z)'×P(z)
P(z)' = 6/12
Now us have 5 lites Z
P(z) = 5/11
P(both z) = (6/12)×(5/11)
= 22.72%
________________
Last example:
P(y then z) = P(y)×P(z)
We have 4 lites y
P(y) = 4/12
Now us have 11 lites on the bag
P(z) = 6/11
P(y then z) = (4/12)×(6/11)
= 18,18%
This would be your answers.
Hope this helps
Answer:
800n+1050
Step-by-step explanation:
800(n+1)+250 = 800n+800+250 = 800n+1050.
