If a coin has been altered so that the probability of heads coming up is 3/10 , then the probability of tails coming up is 7/10. true or false

This is true. When there are only two options and the probability of one option is given, then the probability of the other option is (1 - the probability of the given option). Therefore 1 - 3/10 = 7/10

answer is : muchas/tipicas

have a nice day!

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
