Answer:

Step-by-step explanation:

total: 200 employees of a company

119 had investments in stock funds

99 had investments in bond funds

65 had investments in money market funds

47 had investments in stock funds and bond funds

33 had investments in stock funds and money market funds

33 had investments in bond funds and money market funds

21 had investments in stock funds, bond funds, and money market funds.

See Venn diagram attached

(a) What is the probability that an employee of the company chosen at random had investments in exactly two kinds of investment funds? (Enter your answer to three decimal places.)

Exactly 2 kinds: 26+12+12 = 50

50/200 = 0.25

(b) What is the probability that an employee of the company chosen at random had investments in exactly one kind of investment fund? (Enter your answer to two decimal places.)

Exactly one kind: 60+40+20 = 120

120/200 = 0.60

(c) What is the probability that an employee of the company chosen at random had no investment in any of the three types of funds? (Enter your answer to three decimal places.)

60+40+20+26+12+12+21=191

200-191 = 9

9/200 = 0.045

What is the formula for gigabytes to bytes
emmasim [6.3K]

Bit: Computers deal with binary digits, or bits for short. A bit can be 0 or 1, equivalent or off or on.

Byte: One byte is eight binary digits, such as 1111001.

Kilobyte (KB): The smallest file stored on a smartphone, tablet or PC is typically four kilobytes (4KB) in size. A kilobyte is 1024 bytes. Therefore 1KB is the same as 1024 x 8 = 8192 binary digits.

Megabyte (MB): 1024KB equals one megabyte (MB).

Gigabyte (GB): There are 1024MB in one gigabyte.

Terabyte (TB): There are 1024GB in one terabyte (TB)

I Hope this Helps!!

What is the length of the altitude
egoroff_w [7]

There are a few ways you could go about this. One way is to use sin 60 to calculate the value of a. In other words, sin 60 = a / 8sqrt(3). Simplifying that you should get a = 12.


So F should be the right answer.


Cheers and good luck
