Answer:

0.005371

Step-by-step explanation:

Given that a fair coin is tossed 11 times.

Since coin is fair probability for head p = 0.5 and q = prob for tail =0.5

Each trial is independent of the other. Hence X no of heads is binomial with $n = 11 and p =0.5$

Prob for getting 10 heads out of 11 tosses

=P(X=10)

= $11C10 (0.5)^{10} (0.5)\\= 0.005371$

Nina [5.8K]

Answer:

In year 2039 both the events will happen again.

Step-by-step explanation:

We are given the following in the question:

Family reunion:

Every 7 year

Update the family tree:

Every 6 years

1997 was the year when they had a family reunion as well as they updated their family tree.

We have to find the year in which both the events will occur together.

We find the lowest common multiple of 7 and 6.

$L.C.M(7,6) = 7\times 6 = 42$

Thus, after 42 years both the event will happen again.

Year:

$1997 + 42 = 2039$

Thus, in year 2039 both the events will happen again.

tamaranim1 [39]

Answer:

Fadil earns $60 for each tv sold.

Step-by-step explanation;

13 (30) = 390

390 is the cost of all the warranties.

Subtract 390 from 1,170 to find the fixed amount for 13 tvs.

1,170 - 390 = 780

Divide 780 by 13 to find the fixed amount per tv.

780 ÷ 13 = 60
