2 beginner, 6 intermediate, 3 advanced...total of 11
P(advanced) = 3/11
replaced
P(beginner) = 2/11
P(both) = 3/11 * 2/11 = 6/121 <=
The answer is 15 cm. Hope I could be of help! ; )
Answer:
33×33+33-33÷0=infinity
33×33=1089
33-33=0
Taking L.H.S
=33×33+(33-33)÷0
=1089+0÷0
=1089÷0
=infinity
L.H.S=R.H.S
Step-by-step explanation:
In order to solve a negative exponent, you have to consider the multiplicative inverse of the base:

So, if we solve the negative exponent on the left hand side, we have

which is the right hand side.
It would be 56/177. If you need any question how I got that answer, ask me.. :)
