Answer:
Probability of a dice rolling a number less than 3 is 2/6 = 1/3
Probability of dice spinning a number less than 6 is 5/6
Step-by-step explanation:
Number less than 3:
Chances of no. Being 1 and 2, not including 3, is 1/6 individually.
Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3
Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6
Answer:
A) 1/12 lb.
.. (1 2/3)/20 = 1/20 + (2/3)*(1/20)
.. = 1/20 + 1/30
.. = 3/60 + 2/60
.. = 5/60 = 1/12
It's b 165 tell me if am wrong
Answer: The theoretical probability of the coin landing heads up is 0.7
Step-by-step explanation:
Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:
Mathematically speaking:
42 /60 = 0.7 (decimal form)
The theoretical probability of the coin landing heads up is 0.7
For the or percentage form we simply multiply the result by 100:
0.7 (100) = 70%
Feel free to ask for more if needed or if you did not understand something.
x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
