For one toss of a certain coin, the probability that the outcome is heads is 0.6. If this coin is tossed 5 times, which of the following is the probability that the outcome will be heads at least 4 times?

A. (0.6)5(0.6)5

B. 2(0.6)42(0.6)4

C. 3(0.6)43(0.6)4

D. 4(0.6)4(0.4)+(0.6)54(0.6)4(0.4)+(0. 6)5

E. 5(0.6)4(0.4)+(0.6)5

P(x≥4) = 0.337

Step-by-step explanation: p = probability of getting head = 0.6, probability of not getting head = q = 1 - 0.6 =0.4

n = number of times experiment was performed = 5

We are to find

P(x≥4) = 1 - P(x≤3)

We can get the value of P(x≤3) using a cumulative binomial probability table.

P(x≤3) = 0.663

P(x≥4) = 1 - 0.663

P(x≥4) = 0.337

i need a picture

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
