What are the chances of getting pregnant while on pill vs using condoms with spermicidal lubricant.?

7% pill/29% spermici. Effectiveness with contraception is reported as either the lowest expected rate (l) (with motivated patients who are reminded - in a clinical trial, for ex.) or the typical rate (t)- seen in a general sampling of the community - at random. The pill ranges from 0.3% (l) to 8% (t) and spermicide ranges from 18% (l) to 29% (t). Hope this helps.
