63 x 4 = 2x2=3 - 17? Simplified form of this expression: The chosen topic is not meant for use with this type of problem.
So instead I will simplify the matrix, if you simply the matrix, the ANSWER will be: 252 = 2x^2 = -14
The "successful" region has half the size of the whole triangle, so by similar triangles, the probability that the area of triangle XYD is at most 12 is 1/4.
10 pieces of silverware laid in a row if 3 are identical spoons, 4 are identical forks, and 3 are identical knifes
The arrangement of 'm' objects on which 'n' objects are of same kind is 
Given: 10 pieces of silverware so its 10!
3 are identical spoons so its 3!
4 are identical forks so its 4!
and 3 are identical knifes so its 3!
Arrangements made =

Answer:
1/10 or 0.1
Step-by-step explanation:
Probability of occurrence of any event = number of favorable event by total /number of occurrence of event.
For Sarah
Given Number of frames = 18
Number of strikes made by her = 5
Therefore by using the above formula to get the probability of striking by Sarah will be 5/18.
__________________________________________________
For David
Given Number of frames = 25
Number of strikes made by him = 9
Therefore by using the above formula to get the probability of striking by David will be 9/25.
__________________________________________________
Since the event of Sarah and David are mutually independent i.e occurrence of one event does not impact the occurrence of other event.
Probability of occurrence of two mutually independent A and B event with Probability P(A) and Probability P(B) is given by P(A) * P(B).
Therefore probability that they both get a strike on their next frame are mutually independent event with probability 5/18 and 9/25 will be calculated by 5/18 * 9/25 = 1/(2*5) = 1/10.
Angle 4 is 150 because is is corresponding to angle 2
