Answer:
0.4 since the number is non terminating and non repeating therefore it is irrational number.
-78 A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero
15 The number 15 is a rational number. It is an integer and all integers are rational numbers.
0 Yes zero is a rational number. Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer.
Answer:
The probability that Ang wins and is given a mug is 0.125.
Step-by-step explanation:
Denote the events as follows:
R = Rob wins
S = Sonja wins
J = Jack wins
A = Ang wins
T = the winner gets a T-shirt
M = the winner gets a Mug
Since any of the four people could be winner the probability of each person winning is same, i.e.
P (R) = P (S) = P (J) = P (A) = 0.25
There only two prizes to select from.
So, the winning person gets any of the two prizes with probability 0.50.
Consider the tree diagram attached.
Compute the probability that Ang wins and is given a mug as follows:

Thus, the probability that Ang wins and is given a mug is 0.125.
180 degrees is a straight line. It is half of 360 which is a full circle, so if you split the circle in half you'll get a straight line.
