Answer:
1/625
Explanation:
In case of multiplication of numbers with same base, we add the powers.
This means that:
a^x * a^y = a^(x+y)
Applying this to the given, we will find that:
(5^-1) * (5^-3) = 5^(-1-3)
= 5^-4
= 1/625
Hope this helps :)
Since these events are independent, you add the possibilities
the number of cards less than 9 is 32
the number of spades is 13
there are 52 cards in a deck, so you put those numbers over 52
32/52 + 13/52 = 45/52
the answer is 45/52
44 identical red wooden blocks can be arranged in 44! ways
99 identical white wooden blocks can be arranged in 99! Ways
If the 44 red blocks and the 99 white blocks are to be
stacked on top of one another, the number of different color patterns that can
result = 44! x 99!
44! = 2.65827157 x 10^54
99! = 9.33262154 x 10^155
44! x 99! = 2.48086426 x 10^210
Therefore, 2.48086426 x 10^210 different color patterns can result
