|4b-4|+|3-b^3|+2b^3;b=2

Katen [24]

|4b - 4| + |3 - b³| + 2b³

subtitute b = 2 to the expression

|4·2 - 4| + |3 - 2³| + 2·2³ = |8 - 4| + |3 - 8| + 2·8 = |4| + |-5| + 16 = 4 + 5 + 16 = 25

---------------------------------------------

|4b - 4| + |3 - b²| + 2b³

|4·2 - 4| + |3 - 2²| + 2·2³ = |8 - 4| + |3 - 4| + 2·8 = |4| + |-1| + 16 = 4 + 1 + 16 = 21

There are twelve signs of the zodiac. How many people must be present for there to be at least a 50% chance that two or more of

Nutka1998 [239]

Answer:

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.
