What is the P(1,6,4) on 3 rolls of a dice? show how you got the answer!
julia-pushkina [17]

Answer:

<h2>1/9</h2>

Step-by-step explanation:

Given the sample space of a die S=(1,2,3,4,5,6)

and the sample size=6

the probability of obtaining the number 1 Pr(1)= 1/6= 1/6

the probability of obtaining the number 6 Pr(1)= 6/6= 1

the probability of obtaining the number 4 Pr(1)= 4/6= 2/3

Hence the probability of   P(1,6,4) = \frac{1}{6} *1 *\frac{2}{3} =\frac{2}{18} = \frac{1}{9} \\

The mean weight 20 students in a room is 65 kg one student one student who weight is 88kg went into the room what is the new mea
umka2103 [35]

The new mean is 66.09

<u>Explanation:</u>

Mean weight of 20 students = 65kg

One student with 88kg entered the room.

New mean = ?

\frac{x_1+x_2+....+x_2_0}{20} = 65

\frac{x_1+x_2+....+x_2_0 + 88}{21} = ?

The above equation can further be written as:

x_1 + x_2 +....+x_2_0 = 65 X 20\\\\x_1 + x_2 +....+x_2_0 = 1300

New mean = \frac{1300 + 88}{21}

                 = 66.09

Therefore, the new mean is 66.09
