Principal amount (P) = $1,000

Rate of interest (r) = 7%

Time period (t) = 4 years

Here we use simple interest formula to calculate interest after 4 years.

I = P × r × t

By putting the value, we get

I = $1,000 × 7% × 4

= $70 × 4

= $280

A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
Snezhnost [94]

Answer:

The answer is " \bold{\frac{2}{3}}"

Step-by-step explanation:

Given set:

\to F \ or\  G = \{ 5,6,7,8,9,10,11,12\}

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

\to P( F\ or \ G) = \frac{8}{12}

                      = \frac{2}{3}

by using the general addition Rule:

\to P(F \cup G) = P(F) +P(G)- P(F \cap G)

                    =\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\
