In a bag there are 90 red counters. the probability is 0.3. how many blue counters?
To find the number of blue counters, we first determine the total number of counters in the bag. Given that the probability of selecting a red counter is 0.3 and there are 90 red counters, we can use the formula for probability: ( P(\text{Red}) = \frac{\text{Number of Red Counters}}{\text{Total Counters}} ). Rearranging, we find that the total number of counters is ( \frac{90}{0.3} = 300 ). Thus, the number of blue counters is ( 300 - 90 = 210 ).

What is the probability drawing a blue marble from a bag of 18 marblesin a bag three of which are blue?
The probability of drawing a blue marble from a bag containing 18 marbles, of which 3 are blue, is calculated by dividing the number of blue marbles by the total number of marbles. Therefore, the probability is ( \frac{3}{18} ), which simplifies to ( \frac{1}{6} ). Thus, the probability of drawing a blue marble is approximately 0.167 or 16.7%.

A bag has 7 blue marbles and 8 purple marbles.What is the probability of picking a blue marble then a purple marble without replacing?
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
What is probability and how does it helps?
Probability is the calculation of the extent to which something is probable (the likelihood of something happening or being the case). Probability helps staticians and other people to have a better understanding of what is to come in the future. Ex: If I have a bag of 10 colored marbles where five of them are blue and five of them are red, once I pull out a certain number of red and blue marbles I still know the ratio of red to blue marbles in the bag though it may have changed.
