Answer:

There was a 1.93% probability of having multiples (twins or more) in 1980.

Step-by-step explanation:

There were 3,612,258 births in the US in 1980.

Of those,

68339 + 1337 = 69676 were multiplies.

So

What was the probability of having multiples (twins or more) in 1980?

P = \frac{69676}{3612258} = 0.0193

There was a 1.93% probability of having multiples (twins or more) in 1980.

Answer:

  • 49.9 years or 50 years later.
  • At year : 2042

Explanation:

use compound interest formula:  \sf \boxed{ \sf P ( \sf 1 + \dfrac{r}{100} )^n}

\rightarrow \s \sf 10( 1 + \dfrac{1.4}{100} )^n = 20

\rightarrow \sf ( 1.014) ^n = 2

\rightarrow \sf n( ln( 1.014) ) = ln(2)

\rightarrow\sf n = \dfrac{ln(2)}{ln( 1.014)}

\rightarrow\sf n = 49.8563 \ years
