5 red, 3 blue, 7 white.....total of 15
probability of 1st drawn being red : 5/15 reduces to 1/3
without replacement
probability of 2nd being red : 4/14 reduces to 2/7
probability of both : 1/3 * 2/7 = 2/21 <==
Answer:
2/3
Step-by-step explanation:
1/3 is the same as 3/9 (multiply 3 to both numerator and denominator) 3/9+3/9 is 6/9. 6/9 can be simplified by dividing 3 to both sides to get 2/3.
2. There are 18 other bottles in the fridge, because .6 of 30 is 18. 30 – 18 is 12, so there are 12 bottles of orange juice and cranberry juice.
4. If the probability of an event is 25%, then the probability of <em>not</em> that event is the other part of 100%. In other words, 1 – .25 = .75.
A. 1
b. 1
c. 1
d. 1/2
2. 1/2
3. Yes they did break it because there are 3 wholes.
Answer:
The value of T is 55°
Step-by-step explanation:
Using the theorem of parallel and equality,the angle of unknown angle equals to opposite one.
Or at least if you noticed,that angle is perpendicular,then 35+90=125;
180-125=55°
