Answer:

Probability of a dice rolling a number less than 3 is 2/6 = 1/3

Probability of dice spinning a number less than 6 is 5/6

Step-by-step explanation:

Number less than 3:

Chances of no. Being 1 and 2, not including 3, is 1/6 individually.

Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3

Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6

Solution:

we are given that

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.

As we know

6 teacheras can be selected out of 30 teacher in ${30}_C_6$ ways.

${30}_C_6=\frac{30!}{6!24!}\\
\\ {30}_C_6=\frac{25*26*27*28*29*30}{1*2*3*4*5*6}\\
\\ {30}_C_6=593775$

Hence the required number of ways is 593775.

Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

$15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12$
