Suppose students are independent from one another. 63% of students are using Mr. Martin's new social media app, Mar-tin-stagram.

Answer:

Probability that both of them use it = 0.3945

Step-by-step explanation:

Given:

Student use app = 63%

Number of chosen student = 2

Computation:

Assume total number of student = 100%

So, probability that both of them use it.

⁶³C₂ / ¹⁰⁰C₂

\frac{\frac{63!}{2! 61!} }{\frac{100!}{2! 98! } } \\\\\frac{63\times 62}{100 \times 99} \\\\\frac{3,906}{9,900} \\\\0.3945

Therefore, probability that both of them use it = 0.3945

Ratling [72]

Answer:

If the discs were measured to the nearest milimetre, it might be possible, that they are actually 1.64cm wide instead of only 1.64cm as shown.

Therefore the box would fill up much quicker and there will not be enough space.

Step-by-step explanation:

1.6cm * 16 discs = 25.6cm (would fit)

1.64cm * 16 discs = 26.24cm (would not fit)
