Answer:
4.39% theoretical probability of this happening
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it lands on heads, or it lands on tails. The probability of a coin landing on heads is independent of other coins. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
Theoretically, a fair coin
Equally as likely to land on heads or tails, so 
10 coins:
This means that 
What is the theoretical probability of this happening?
This is P(X = 2).


4.39% theoretical probability of this happening
Answer:
One angle measures 150 degrees.
The second angle is 30 degrees.
Step-by-step explanation:
Answer:
The lcm is; 40b^2n^3
Step-by-step explanation:
There are no common factors between the two expressions and as such the lcm will be found by obtaining the product of he two;
8b^2*5n^3 = 40b^2n^3
Two decimals that are equivalent to 9.50 are 9.5 and 9.500
1/3 of 1/4 is the same as 2/6 of 2/8
(easier for me this way)
2/6 is 0.33
2/8 is 0.25 so you are in essence finding roughly 0.8333
that would be equal to the diagram at the bottom right
The other question is (i believe) 1/5 of 5/6
1/5 is 0.2, 5/6 is 0.833
another way to do it is to divide 833 by 5 is 166.6 so it would be 0.166
that would (i think) be the top right
