Answer:

Probability of getting at least one 2 equals 0.5177

Step-by-step explanation:

The probability of at least one success is

P=1-(1-p)^{n}

where,

'p' is probability of success of 1 trail

'n' is number of events

We have probability of getting 2 is 1/6 thus 'p' = 1/6

Applying values we get

P=1-(1-\frac{1}{6})^{4}\\\\P= 0.51177

C(1)=−20<br> c(n)=c(n−1)+10<br><br> Find the second term in the sequence. <br> ​
svet-max [94.6K]

Answer:

c(2) = -10

Step-by-step explanation:

The first equation says that the first term of the sequence is -20.

The second equation is saying that to find any term of the sequence, add 10 to the previous term.

c(2) = c(2-1) + 10

c(2) = c(1) + 10

c(2) = -20  + 10 = -10

Find the consecutive even integers such as the sum of the larger and 3 times the smaller is 234
Masja [62]

Answer:

The two numbers are 58 and 60

Step-by-step explanation:

let the two numbers be x and y

then:

y+3x=234

since the two numbers are consecutive even integers then y=x+2

and since y+3x=234

then (x+2)+3x=234

then 4x+2=234

then 4x=234–2

then x=232/4=58

then the other number (y) = x+2= 58+2=60
