Answer:

A coin is tossed 4 times. So the sample space is {HHHH, HHHT, HHTT, HTTT, TTTT, TTTH, TTHH, THHH, HTHT, THTH, HTHH, HHTH, HTTH, THHT, THTT, TTHT}

There are 16 sample points. This can be found out by knowing how many objects(or times the same object) is tossed/rolled(for a dice). Sample points = (Outcomes)^no. Of times

16 = 2^4

The answer is 4/16 = 1/4

Hope this helps!

Please only answer if you know the correct answer! Will give brainliest and points!
Mandarinka [93]

Step-by-step explanation:

845/1160 = 0.728

116.5/174 = 0.669

42.25/58 = 0.728

23.4/29 = 0.806

16.9/23.2 = 0.728

25.35/34.8 = 0.728

Hence the 2nd, 4th and 5th options are correct.

The sum of two numbers is 27 and the difference is 19. Find the 2 numbers.
zhuklara [117]

Answer:

the sum of two numbers is 27. their difference is 5. find the number

Step-by-step explanation:

Let x be the first number and y be the second number    ...   so we have

x + y  = 27

x - y  =   5            Adding the equations, we have

2x = 32                Dividing through by 2, we have

x = 16                  And substituting  or x in the first equation, we have

16 + y  = 27         Subtract 16 from both sides  

y = 11
