a jar contains 30 red, 40 blue, and 50 white buttons. you pick one button at random, find the probability that is not white
Jet001 [13]

Answer:

<em>The probability that the button is not white is </em><em>0.583</em>

Step-by-step explanation:

The jar contains 30 red, 40 blue, and 50 white buttons.

In total there are 120 buttons in the jar. So,

|\ S\ |=120

Let us assume that, A be the event of picking white buttons, so

|\ A\ |=50

So the probability of picking white button is,

P(A)=\dfrac{|\ A\ |}{|\ S\ |}=\dfrac{50}{120}

Then the event A^c will be not picking up white buttons, so the probability of not picking up white buttons is,

P(A^c)=1-P(A)=1-\dfrac{50}{120}=\dfrac{70}{120}=\dfrac{7}{12}=0.583

lesya692 [45]

Answer:

Probabilty= 7.66*10^-3

Step-by-step explanation:

A box contains 65 balls numbered from 1 to 65.

9 balls are drawn with replacement.

Probabilty of selecting a number = 1/65

Probabilty of selecting a number

= 0.0154

Probabilty of at least 2 numbers out of 9 selected to have Same number

Probabilty= 9C2(0.0154)^2(0.9846)^7

Probabilty= 7.66*10^-3

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Oxana [17]

Answer:

6m + n + 2

Step-by-step explanation:

[7m + 3n - 11 - 2m] + [n + 5 - -m - 3n + 8]

[5m + 3n - 11] + [n + 5 + m - 3n + 8]

5m + 3n - 11 + (-2n + 13 + m)

5m + 3n - 11 - 2n + 13 + m

6m + n + 2
