Step-by-step explanation:
Given that each zodiac sign occupies 1/12 of a year.
Then the minimum number of persons for Y[all different signs] < 0.5,
The probability of at least two having the same sign is 1 minus the probability of all having different signs.
This can be represented as A [at least 2 person share the same sign] = 1 - Y[all different signs] must be > 0.5
Therefore we have 1 - 12/12 *11/12 * 10/12 *9/12 *8/12 = 0.38
This implies that the lowest number will be found to be 5
Hence, the correct answer is 5.
Answer:
A
Step-by-step explanation:
find the area of the inner triangle and then multiply it by 4
Answer:
ST = 23
RU = 8
SV = 5
SU = 10
Step-by-step explanation:
UV = SV = 5
ST = UT = 23
RU = RS = 8
SU = SV + UV = 5 + 5 = 10
