Answer:
The required probability is, 0.78
Step-by-step explanation:
There are, (52 - 13) = 39 cards which are not spade
5 cards can be chosen from the deck of 52 cards in
ways
and out of these 5 choices, none of them will be spade in,
ways
So,
P(None of the chosen cards is spade)
=
Hence,
P(out of these 5 choices, at least one card is spade)
= 0.78
Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+
=
Now, arrange the equation
So, =
-
<u>Taking L.C.M on right hand side </u>
Or, =
Or, =
Or, x =
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
Answer:
Step-by-step explanation:
Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)
This gives us the fraction:
We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction:
Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:
which can be simplified in exponent form as:
, now all we have to do is divide the 24 by the 3, to get 8
This gives us the answer:
