The probability of rolling a value of 1 or 6 for the unfair die ls 1/2
The probability of an event is given as :
P(event) = Required outcome / Total possible outcomes
Let the probability of other numbers on the die = n
Therefore, Probability of 6 = 3n
The Cummulative probability can be expressed thus since the Cummulative sun must be equal to 1 :
Other values on the die are 5 ; 1, 2, 3, 4, and 5
5n + 3n = 1
8n = 1
n = 1/8
The probability of other numbers = 1/8
Probability of 6 = 3(1/8) = 3/8
Probability of (1 or 6) = P(1) + P(6) = 1/8 + 3/8 = 4/8 = 1/2
Therefore, the probability of obtaining 1 or 6 is 0.5

Answer:
1/2.
Step-by-step explanation:
Probability totals must add up to 1.
P = probability.
If P(any number other than 6) = x, then P(6) = 3x, so
3x + 5x = 1
x = 1/8
P(6) = 3/8 and P(not 6) = 1/8
Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).
AB = AD
AB = AC
AB= AC times AE/AD
AB= AE times AD/AB
Answer:
AB= AC times AE/AD
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
so
In this problem
AB/AC=AE/AD
solve for AB
AB=(AC)(AE)/AD
Answer:
AB= AC times AE/AD
Step-by-step explanation:
AB is on the segment AC, therefore it is proportional to AC.
In order to fulfill the requirement that triangle ABE is a smaller scaled replica of triangle ACD, a scale factor must be applied to the sides of the original figure; in this case, the factor is AE/AD.
Answer:
B) {8.71}
Step-by-step explanation:
3. l.c.m=28
28×3/7=28×b-7/4
4×3=7(b-7)
12=7b-49
12+49=7b
61=7b
61/7=7b/7
8.71=b
b=8.71.
