Answer: The probability is 0.64
Step-by-step explanation: There are 39 counters in a bag. 14 of them are red and the remaining 25 are blue. Every time a counter is taken from the bag at random, there are altogether 39 possibilities regardless of the color of the counter drawn.
Also if we want to pick a blue counter from the whole lot, there are 25 possible chances.
Therefore the probability of picking a blue counter is shown as follows;
P(Blue) = Number of required outcomes ÷ Number of total possible outcomes
P(Blue) = 25/39
P(Blue) = 0.64
Therefore, the probability of taking a blue counter is 0.64 (or 64%)

Answer:
(-3+) /2, (3+) / 2 which is approx -3.791 and 0.791
Step-by-step explanation:
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
Answer:
g(1) = -65; g(n) = g(n-1) -15
Step-by-step explanation:
Using n = 1, 2, 3, we can find the first three terms of the sequence:
g(1) = -50 -15 = -65
g(2) = -50 -15(2) = -80
g(3) = -50 -15(3) = -95
The first term of the arithmetic sequence is -65, so that is g(1). Each next term is 15 less than the one before, so the recursive formula is ...
g(n) = g(n-1) -15
The complete recursive function definition requires both parts:
g(1) = -65
g(n) = g(n-1) -15
