The probability of drawing only one red card in two draws without replacement is given by:
The probability of drawing two red cards in two draws without replacement isgiven by:
The events 'draw one red card' and 'draw two red cards' are mutually exclusive. Therefore the probability of drawing at least one red card is 0.51 + 0.245 = 0.755.

Answer: 0.1
Step-by-step explanation:
If we spin a fair spinner numbered 1 - 5 and flips a fair coin.
Then, the possible outcomes will be :-
i.e. total 10 possible outcomes.
The favorable outcomes = a 2 and a head i.e. only 1 .
Now, the probability of obtaining a 2 and a head will be :_
Hence, the probability of obtaining a 2 and a head = 0.1
The ratio is 4:3:1
let the ratio be 4x:3x:x
according to the question,4x+3x+x=40
8x=40
x=5
therefore amount of gravel=x*4=5*4=20
amount of sand=5*3=15
amount of cement=5*1=5

Answer:
False
Step-by-step explanation:
The volume of a right cylinder is given by the formula:
And the volume if a oblique cylinder is <em>also</em> given by the formula:
Regardless of the height, if the radius are different, then the volume would not be the same.
