Answer:
5/156
Step-by-step explanation:
First, how many pieces?
1 red+ 5 green + 7 yellow = 13 pieces
We draw a piece
The probability it is green
P(green) = number of green/ total
= 5/13
Now there are only 12 pieces left
Probability the second piece drawn is red
P(red with 1 piece removed) = number of red/ total left
= 1/12
P(green, then red) = P(green) * P(red with 1 piece removed)
= 5/13 *1/12
=5/156
Answer:
29
Step-by-step explanation:
x+11÷8=5
5 × 8 = 40
40- 11 = 29
29 + 11 ÷ 8 =5
Answer:
0.25
Step-by-step explanation:
This is the question on conditional probability
Let A - the quadrilateral has four right angles
B - the quadrilateral has four equal side lengths
Required probability = P(B/A)
By definition of continuous probability


P(A) = 
Hence given probability = 
Answer:
52
Step-by-step explanation:
14+13= 27+2=29+23=52
