Answer:
(b)0.56
(c)0.38
Step-by-step explanation:
(a)
P(Ben Pass) =0.8
Therefore: P(Ben fails)=1-0.8 =0.2
P(Tom Pass) =0.7
Therefore: P(Tom fails)=1-0.7 =0.3
See attached for the completed tree diagram
(b)Probability that both will pass
P(both will pass)=P(Ben pass and Tom pass)
=P(Ben pass) X P(Tom pass)
=0.8 X 0.7
=0.56
(c)The probability that only one of them will pass
Since either Tom or Ben can pass, we have:
P(only one of them will pass)
=P(Ben pass and Tom fails OR Ben Fails and Tom Pass)
=P(Ben pass and Tom fails)+P(Ben Fails and Tom Pass)
=(0.8 X 0.3) + (0.2 X 0.7)
=0.24 + 0.14
=0.38

Answer:
The answer is B
Step-by-step explanation:
Answer:
The correct option is;
B. a. Whole number b. Irrational number
Step-by-step explanation:
The height, h of the equilateral triangle = 3·√2·s
The item by which equilateral triangle is made = 2-inch toothpicks
Therefore, we have;
The sides of the equilateral triangle = Comprises multiples of 2 inches
Therefore, the sides of the equilateral triangle is a whole number
The height of the triangle is the product of the side and (√3)/2
Therefore, the height of the triangle is an irrational number
The correct option is A. a. Whole number b. Irrational number.
A whole number are the positive counting numbers, 0, 1, 2, ..., while an integer includes negative numbers which is not possible for a real triangle.
Answer: The probability is 0.46%.
The chance of each given event happening is 1/6 because there are 6 different number on the dice and only 1 number is chose.
Therefore to find the combined probability, we have to multiply all the individual probabilities.
(1/6) x (1/6) x (1/6)
Or
(1/6)^3
The answer is about 0.46%,
