How many subsets of at least one element does a set of seven elements have?

Tomtit [17]

$\boxed{\large{\bold{\blue{ANSWER~:) }}}}$

For each subset it can either contain or not contain an element. For each element, there are 2 possibilities. Multiplying these together we get 27 or 128 subsets. For generalisation the total number of subsets of a set containing n elements is 2 to the power n.

An ion channel can be in either open (O) or closed (C) states. If it is open, then it has probability 0.1 of closing in 1 micros

iragen [17]

Answer:

a) P (COO) = 0,135

b) P ( SISI) = 0,00015

Step-by-step explanation:

a) the probability of an ion channel in open position is 50 % 0,5

the probability of an ion channel in close position is 50 % 0,5

probability for the following sequence of states COO

to be closed 0,5 (C)

from (C) to pass to open 0,3 (O)

and to stay O is 0,9

Then the probability of the sequence of states COO is

P (COO) = 0,5 * 0,3 * 0,9

P (COO) = 0,135

b) If people are either infected or susceptible, then

Probability of an individual infected is 0,5

Probability of an individual susceptible is 0,5

to pass from susceptible to infected is 0,05

to pass from infected to susceptible is 0,12

then

P ( SISI) = 0,5 * 0,05*0,12*0,05

P ( SISI) = 0,00015

probability for the following sequence of states COO

Multiply 6/5 x 25/2<br> PLEASE HURRY I NEED IT NOW

FromTheMoon [43]

Answer:

Step-by-step explanation:

65×252=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

6×255×2=15010

Since 150 divided by 10 equals 15 then,

15010=15

Therefore:

65×252=15
