I'm pretty sure it'd be 4/6 and then it'd simplify to 2/3. You add together the possibilities of rolling an odd number (3/6) to the possibilities of getting a number less than 3 (2/6) and then subtract the number that they both had in common (which would've been the number 1). So it'd be 3/6+2/6=5/6 - 1/6. and you'd get 2/3
Answer: The chances are of the probability = 0.0001
Step-by-step explanation:
The normal distribution can be described completely by the two parameters µ and σ.
As always, the mean is the center of the distribution and the standard deviation is the measure of the variation around the mean.

<span>26 black cards of out 52
probability that a black card is chosen first = 26/52 = 1/2
</span>there are 13 heart
with replaced
The probability of then drawing a heart is 13/52 = 1/4 then
<span>the probability that a black card is chosen first and a heart is chosen second
= </span>(1/2)(1/4) = 1/8
answer
1/8
Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
