To group an expression, means that the factors of the expression are to be separated in (), [] or {}.
An expression with a value of 80 is:
The number is given as:
Factorize
Factorize 40
Express as an exponent
Express 20 as 4 x 5
Express 5 as 3 + 2
Express 4 as 2 + 2

Answer:
Step-by-step explanation:
*Missing Part of the Question*
4 stars
5 triangles
3 circles
3 squares
Required
Determine the probability of triangle being first then square being second
Represent the triangle with T and square with S
So, we're solving for P(T n S)
Solving for P(T)
Solving for P(S)
The question implies a probability without replacement;
Hence Total has now been reduced by 1
Total = 14
Recall that
Hence, the required probability is
