The sides of the cubes are numbered 1 through 6. if they are both tossed, what is the probability that they will both be a 3?

Elodia [21]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

the sides of the cubes are numbered 1 through 6,

So,

$P(\text{ getting a 3})=\frac{1}{6}$

if they are both tossed ,

Probability (getting that they will both be a 3) is given by

$=\frac{1}{6}\times \frac{1}{6}\\\\=\frac{1}{36}$

(∵ $\\P(\text{A and B})=P(A\cap B)=P(A).P(B)\\$ )

Therefore, Option 'C' is correct.

An isotope of iodine has a mass of 134 amu. How many neutrons does the

Nina [5.8K]

Answer:

The correct option is C: the isotope of iodine contains 81 neutrons.

Step-by-step explanation:

The mass (A) of the iodine isotope is given by:

$A = Z + N$

Where:

Z: is the number of protons

N: is the number of neutrons

For iodine Z= 53, so if A = 134 the number of neutrons is:

$N = A - Z = 134 - 53 = 81$

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

I hope it helps you!
